2022 Diversity Scholars

Institution: Northwestern University
Career Level: Postbaccalaureate
Research Summary: I received a B.S. in psychology from the University of Georgia in 2021. I am currently a research assistant at Northwestern University in the Developmental Mechanisms Lab. Under the direction of Drs. Elizabeth Norton and Lauren Wakschlag, I work on the When 2 Worry Study, investigating early language and mental health trajectories with a focus on language delays and behavioral and emotional development. W2W has allowed me to work with a diverse set of families, conduct child and adult language assessments, and run infant and child electroencephalography (EEG) data collection. The focus of this research is to generate a clearer model of language delay in toddlerhood and help parents and clinicians better identify when to be concerned about children's language development.

Institution: New York University
Career Level: Postdoctoral
Research Summary: I am a postdoctoral researcher in the Language Experience and Acquisition Research at NYU Lab (LEARN Lab). One of my research interests is the early language development of individuals with autism. The goal of our diversity supplement project is to develop an eye-tracking measure that will assess the receptive language vocabulary of young children who are on the autism spectrum.

Institution: University of Miami Miller School of Medicine
Career Level: Postbaccalaureate
Research Summary: The Chaudhari lab at the University of Miami Miller School of Medicine focuses on the gustatory sensory pathway which, at its core, involves the first detection of taste stimuli at the taste bud cells and subsequent sensory transmission by way of the geniculate ganglion neurons to the central nervous system. The lab studies these neurons at the molecular, anatomical, and functional levels. My 2020-2022 diversity supplement research project looked at how a new capsid of the adeno-associated virus (AAV-PHP.S) could be used to label peripheral sensory ganglion neurons with fluorescent markers, including in a Cre-dependent fashion to label selective neuronal cell types. We used the method to view real-time physiological activity of selected subsets of cranial ganglion sensory neurons (Asencor, et al., eNeuro. 2022 Jun 6;9(3): ENEURO. 0373-21.2022). I am now a first-year neuroscience Ph.D. student at the University of California San Francisco and in the midst of laboratory rotations.

Institution: Massachusetts Eye and Ear
Career Level: Undergraduate
Research Summary: My interest in conducting research in the lab of Artur A. Indzhykulian, M.D., Ph.D., stemmed from witnessing my mother suffer from Usher syndrome type 2A. Having the opportunity to contribute to projects ameliorating the effects of hearing conditions has been incredibly meaningful to me. I have received training in structural biology and biochemistry and have contributed to the lab’s work on characterizing the stability and structural properties of IPT domains 1 and 2 of polycystic kidney and hepatic disease 1-like 1 (PKHD1L1). I have learned how to perform primer design, DNA cloning, bacterial protein expression, and X-ray protein crystallography and have used these skills, alongside others, to advance the PKHD1L1 project and assist with an Usher syndrome type 1F gene therapy project as well. In the future, I hope to continue researching the pathophysiology of hearing-ocular conditions such as Usher syndrome type 2A.

Institution: University of North Carolina at Chapel Hill
Career Level: Postbaccalaureate
Research Summary: Although higher-order cortical areas are known to extract complex sensory features such as vocal communications, the circuits underlying these integrative functions are still unclear. Higher-order cortices are generally considered to receive pre-processed inputs from the primary cortices. However, recent studies across sensory modalities suggest that secondary cortices may also receive sensory inputs directly from the periphery, bypassing primary cortical areas. As a research technician at UNC Chapel Hill, my research focuses on delineating the ascending pathways from the periphery to the mouse secondary auditory cortex, using anatomical tracing, in vivo electrophysiology, and optogenetics. The results will inform us of the circuit mechanisms underlying the integrative functions of the secondary auditory cortex and provide insights into the general principles underlying how higher-order cortices integrate parallel ascending pathways to generate a coherent percept.

Institution: Rutgers University
Career Level: Predoctoral
Research Summary: I am currently a Ph.D. candidate in the lab of Kasia Bieszczad, Ph.D. As a neuroscientist, my interests lie in the epigenetic mechanisms that underlie learning and memory. My work currently investigates how one epigenetic regulator, HDAC3, targets genes in the adult auditory cortex that are involved in long-term auditory memory formation. My findings will provide genetic targets of epigenetic regulation that may be critical for facilitating the experience-dependent neural processes required for behavioral adaptation. Epigenetic mechanisms are likely key to producing the most robust and long-lasting functional changes in the brain, which are critical for long-term memory formation.

Institution: University of Pittsburgh
Career Level: Predoctoral
Research Summary: I am an M.D./Ph.D. student studying the neurobiological bases of speech processing at the Center for Neuroscience and Department of Neurosurgery at the University of Pittsburgh. My research leverages direct intracerebral recordings across the auditory cortex from patients undergoing monitoring with stereoelectroencephalography (sEEG) for intractable epilepsy to examine the central hypothesis that listening context systematically affects the encoding of acoustic dimensions in signaling phonemes. My work aims to investigate how human cortical response to speech represents perceptual weights of phonemes, and how connectivity flexibly adjusts to represent perceptual weights under different listening demands in experimental and naturalistic speech paradigms. This will establish how feedback and feedforward signaling between primary auditory cortex (HG) and STP (planum temporale) informs the flexible encoding of perceptual weight of acoustic dimensions, as well as how experimental observations compare to neural encoding during natural speech. Understanding this phenomenon at the neural level is essential for building a complete picture of how the brain perceives human speech. Our scientific premise is that next-generation neurobiological models must account for adaptive plasticity—the dynamic, flexible mapping of speech acoustics to perception.

Institution: University of Connecticut
Career Level: Undergraduate
Research Summary: Theory of mind (ToM) is the ability to attribute mental states to oneself and others. Studies including typically developing (TD) children and children with autism spectrum disorder (ASD) have shown that children with ASD struggle more often with ToM tasks than TD children. Our big-picture project is investigating the degree to which the language development of children with ASD can impact the development of their ToM. My specific study further explores the potential relationship between ToM and language by examining the use of internal state language by children and parents, using both manual and computer-based coding of children’s narratives and their interactions with their parent.

Institution: Mayo Clinic
Career Level: Undergraduate
Research Summary: I am currently a freshman undergraduate student at Duke University, where I am majoring in psychology and biology. During my diversity summer internship at Mayo Clinic, I performed acoustic measurements of diadochokinetic speech tasks in patients with primary progressive apraxia of speech and examined how these rates are associated with clinical markers of severity and regional 18F-fluorodeoxyglucose positron emission tomography (PET) variables. This work helped determine the value of acoustic measurements as objective markers of speech impairment in primary progressive apraxia of speech.

Institution: Gallaudet University
Career Level: Undergraduate
Research Summary: I am an undergraduate research assistant supported on a diversity supplement to an U01 grant that focuses on promoting cancer screening adherence among deaf, deafblind, and hard of hearing (DDBHH) people. In addition to participating in all aspects of this U01 project, I am working with my co-mentors on a paper that examines the role of DDBHH community health navigators in strengthening the relationship between DDBHH patients and their healthcare providers. After graduation, I plan to take a gap year and do postbaccalaureate research before attending medical school.

Institution: Johns Hopkins University School of Medicine
Career Level: Predoctoral (medical school student on a research year between years 3 and 4)
Research Summary: I am a medical student at Johns Hopkins University School of Medicine on a research year between my third and fourth years. I was born in Bogotá, Colombia, and raised in Houston. I double majored in biology and theatre at the University of Alabama in Tuscaloosa. I am spending my research year in Dr. Alexander Hillel's Otolaryngology Translational Research Lab. I am studying wound healing and fibrosis via the pathogenesis of iatrogenic laryngotracheal stenosis (iLTS) and idiopathic subglottic stenosis (iSGS). The goal of Dr. Hillel's lab is to establish the etiology of iSGS by studying the local immune environment, as well as to develop better treatment options for iLTS and iSGS patient populations. I plan on applying into residency for otolaryngology-head and neck surgery and hope to continue translational tissue engineering research in a Ph.D. program.

Institution: Rutgers University
Career Level: Postdoctoral
Research Summary: I received my Ph.D. in biology at Rutgers University – Newark, where I was trained as a developmental neuroscientist. My current interest is to understand the epigenetic changes during development of inner ear neurosensory progenitors. The diversity supplement allows me to focus on whether CHD7 regulates non-canonical DNA regulatory elements such as anti-sense promoters when otic neurosensory progenitors differentiate into auditory neurons. Using genome editing tools such as CRISPRi, I will specifically block CHD7 binding at anti-sense promoters and determine whether neuronal differentiation is altered. The research will identify new mechanisms that underlie inner ear development.

Institution: University of Pittsburgh
Career Level: Undergraduate
Research Summary: I am an undergraduate student at Johns Hopkins University. As a native Spanish speaker, I have always been interested in the cognitive neuroscience of speech development and language learning, and specifically in the advancement of auditory learning methods for learning impairments and auditory processing deficits. For my diversity supplement project at the University of Pittsburgh, I am currently working to uncover neural biomarkers of auditory health. My work focuses on using electroencephalography (EEG), a non-invasive maker of brain processing, to analyze the coalescence of multiple brain areas necessary to process acoustic cues in real-time speech.

Institution: The Ohio State University
Career Level: Junior faculty
Research Summary: I am an assistant professor of social work at The Ohio State University. My research focuses on building resilience in grandfamilies. I am committed to understanding the strengths and challenges of grandfamilies in order to create and deliver interventions that encourage self-care, communication, and empowerment. I am also interested in culturally grounded research and the development of culturally grounded measures and interventions. Some of my current projects include conducting social network analysis to examine the relationship between social support and resilience in grandparents raising grandchildren; assessing the human service landscape in central Ohio as it relates to grandparents raising their grandchildren; and implementing a self-care program for grandparents raising grandchildren.

Institution: Northeastern University
Career Level: Postbaccalaureate
Research Summary: I graduated from Wellesley College with a B.A. in neuroscience. In 2021, I joined the Language Acquisition and Brain Lab (the QLAB) directed by Zhenghan Qi, M.D., Ph.D., at Northeastern University, where the research focus is on the neurobiological organization of language and how language learning context may affect language differences in typical and atypical development. With the support of the diversity supplement, I have embraced opportunities as a lab manager to conduct behavioral and fMRI sessions with children and adults, improve my lab management skills through completing the Society of Behavioral Medicine (SBM) Good Clinical Practice Training, and enrich my awareness in the field by attending conferences such as the 14th Annual Society for the Neurobiology of Language (SNL) Conference. I am blessed to be among such genuine researchers, and I look forward to facilitating crucial research and refining methods that will lend more insight into language differences in diverse populations.

Institution: University of California San Diego
Career Level: Postbaccalaureate
Research Summary: I received a B.S. in biochemistry at UC San Diego, where I am now a research assistant with the Komiyama Lab. Our laboratory studies the activity of neuronal ensembles and how it might change with experience and learning. My research focuses on the mechanisms that govern the plasticity of adult-born neurons in the olfactory bulb. Understanding how behavior contexts affect brain plasticity and memory abilities can impact future diagnosis and treatments of memory disorders such as dementia and Alzheimer’s disease.

Institution: University of Pittsburgh
Career Level: Undergraduate
Research Summary: I am a senior at the University of Pittsburgh, majoring in communication science and minoring in Spanish. I am currently an undergraduate research assistant in the Brain Systems for Language Lab, and my long-term goal is to become a speech-language pathologist who supports bilingual children who have communication disorders. The overall goal of the research project I am working on is to provide a mechanistic understanding of speech sound processing in children who stutter. We are assessing the rapid transformation from acoustic encoding to perception of phonetic/syllable categories in children who stutter. This requires complementary evidence from multiple non-invasive neuroimaging methods, including EEG and MRI.

Institution: Gallaudet University
Career Level: Postbaccalaureate
Research Summary: In my training with the Center for Deaf Health Equity at Gallaudet University, we want to explore the relationship between cancer worry, cancer beliefs, and cancer screening behavior within the deaf, DeafBlind, and hard of hearing (DDBHH) population. This investigation aligns with the Center’s U01 grant that advances cancer health equity among diverse DDBHH populations by leveraging technology-enhanced approaches and community health workers who use American Sign Language (ASL). Among DDBHH people who use ASL, there are documented reports of difficulties in understanding cancer health information in print, accessing clinical services for screenings, and understanding and following treatment-related directives if the screening results warrant a cancer diagnosis. By elucidating the relationship between cancer worry and cancer screening behaviors in DDBHH people, we aim to identify optimal strategies for resolving cancer worry-related barriers to receiving cancer prevention and screening.

Institution: The City College of New York
Career Level: Postdoctoral
Research Summary: We focus on the maturation of auditory cortical circuitry and the emergence of hemispheric asymmetry in neuronal circuit architecture. Failure to develop hemispheric specializations in auditory circuits is a common endophenotype in communication disorders. A better understanding of the functional connectivity programs guiding healthy development will provide a comparative template to mechanistically examine deficiencies found in human neurodevelopmental communication disorders. I received my B.S.E in biomedical engineering from Duke University and my Ph.D. in bioengineering from the University of Pennsylvania. I was a postdoctoral fellow in neuroscience at Cold Spring Harbor and am a current postdoctoral fellow in biology at The City College of New York.

Institution: Duquesne University
Career Level: New/junior investigator
Research Summary: I am a person who stutters, a speech-language pathologist, and an assistant professor at Duquesne University. My research interests include better understanding and predicting individual differences in the experience of stuttering (stammering), understanding how adverse impacts related to the condition develop, and determining how moments of stuttering occur in speech. I am currently investigating the role cognitive-affective processes have on speech production and language formulation processes in stuttering and non-clinical populations. I practice clinically and am actively involved in clinical education regarding stuttering assessment and treatment.

Institution: Columbia University Vagelos College of Physicians and Surgeons
Career Level: Predoctoral
Research Summary: In collaboration with colleagues at Massachusetts Institute of Technology and Massachusetts Eye and Ear, I am working on a project using sheep as a large-animal model to test a novel implantable microphone for fully implantable hearing prosthetics, such as cochlear implants. Specifically, we are developing the surgical approach and bracing mechanism for implantation of the microphone in the middle ear of cadaveric sheep temporal bones, with the long-term goal of live-animal trials. We are also investigating surgical access to the round window membrane in a specific breed of sheep. After this research year, I plan to complete my final year of medical school and apply to otolaryngology residency.

Institution: University of Pittsburgh
Career Level: Undergraduate
Research Summary: The combination of functional magnetic imaging (fMRI) with tasks such as narrative comprehension and picture naming has been used to study brain activation patterns in people with aphasia. However, these previous language mapping paradigms were found to be lacking in feasibility, reliability, and validity. An adaptive semantic matching task was recently developed by Wilson, Yen, and Eriksson (2018) to address these issues, and their results suggest that the procedure is feasible, reliable, and valid for mapping language activation in persons with aphasia. My 2022 summer research project focused on replicating their results in an independent data set collected as part of an ongoing aphasia treatment study.

Institution: The University of Texas at Dallas
Career Level: Predoctoral
Research Summary: Individuals with autism spectrum disorders often experience difficulties with everyday communication. Receptive language ability can be impacted by neural dysfunction along the auditory pathway. My doctoral research is focused on understanding the relationship between neurophysiological responses to sound and functional behavior. My diversity supplement project focuses on evaluating the influence of vagus nerve stimulation paired with sound presentation on anterior auditory field sound-evoked responses in a rat model of autism. The results from my research will contribute to our understanding of the mechanisms of altered auditory processing among individuals with autism spectrum disorders, and will evaluate targeted therapeutic interventions for improving sound processing.

Institution: Boston University
Career Level: Predoctoral
Research Summary: I am currently a doctoral candidate in the lab of Helen Tager-Flusberg, Ph.D. As a developmental and clinical psychologist, I am interested in studying the neurological correlates of language and social communication differences in children and adolescents with autism spectrum disorder (ASD). My work currently investigates receptive language processing in children with ASD who are minimally verbal (i.e., have fewer than 20 spoken words) using functional near-infrared spectroscopy (fNIRS). I am interested in seeing how this population responds to stories that contain references to their specific interests. The findings will be used to help identify the neurological characteristics of children with ASD who respond to individually targeted language. This has important implications for developing novel targeted and intensive language interventions for this group of children.
2021 Diversity Scholars

Institution: New York University
Career Level: Postdoctoral
Research Summary: People with hearing loss exert additional mental effort to understand speech (i.e., more listening effort), and the resulting cognitive fatigue can have long-term negative consequences for quality of life. The neural mechanisms underlying listening effort—and how hearing loss alters this mechanism—are uncertain. I am working towards identifying (in an animal model) a cortical network that supports effortful listening during performance on an auditory perceptual task. I also aim to explore how hearing loss in adolescence disrupts this cortical mechanism. Results from these experiments will provide a better mechanistic understanding of listening effort and may facilitate more effective strategies for intervention and remediation of hearing-loss-induced cognitive deficits.

Institution: University of Miami Miller School of Medicine
Career Level: Postbaccalaureate
Research Summary: After receiving my B.A. in neuroscience from Boston University, I joined the Chaudhari lab at the University of Miami Miller School of Medicine. We focus on the gustatory sensory pathway which, at its core, involves the first detection of taste stimuli at the taste bud cells and subsequent sensory transmission by way of the geniculate ganglion neurons to the central nervous system. Our lab studies these neurons at the molecular, anatomical, and functional levels. My diversity supplement research project looks at how a new capsid of the adeno-associated virus (AAV) can be used to label peripheral sensory ganglion neurons with fluorescent markers, including in a Cre-dependent fashion to label selective neuronal cell types. We used the method to view real-time physiological activity of the gustatory pathway. This work is currently under review for publication.

Institution: New York University
Career Level: Predoctoral
Research Summary: Better understanding the sensory skill development that underlies speech development can help inform best practices in the field of speech-language pathology. Specifically, we are currently studying speech sound perception and oral somatosensory acuity. As a practicing speech-language pathologist, I am currently obtaining, analyzing, and comparing data on development of these two skills in typically developing children and in children with speech sound disorders. This information will be used to tailor individual speech treatments for children in the future.

Institution: Massachusetts General Hospital Institute of Health Professions
Career Level: Predoctoral
Research Summary: I am a speech-language pathologist and Ph.D. student in rehabilitation sciences at the MGH Institute of Health Professions. My research interests are focused on stroke assessment and recovery. This includes examining the appropriateness of commonly utilized clinical assessment practices for historically marginalized populations that are increasingly burdened by poor health outcomes. Additionally, I am interested in disorders affecting stroke populations with comorbid motor deficits, particularly acquired apraxia of speech (AOS). AOS is a unique motor speech disorder that is often caused by stroke. Existing motor learning theories suggest that impairment in AOS arises from impaired feedforward commands which leads to an over-reliance on feedback. My research aims to clarify the role auditory feedback plays in spoken language production in people with aphasia only, and those with concomitant AOS.

Institution: University of Maryland, College Park
Career Level: Predoctoral
Research Summary: I work in the Gaudry lab at the University of Maryland, College Park, in the Neuroscience and Cognitive Sciences (NACS) Program, where we have discovered that the Drosophila 5-HT7 receptor (5- HT7R) is associated with detection of low levels of basal 5-HT in the first olfactory relay center, the antennal lobe (AL). We have also found that signaling in this receptor mediates a subtractive form of gain control that leaves the AL less sensitive to odors. I perform large-scale behavioral assays to examine the role of 5-HT7R-expressing local interneurons in courtship, aggression, and aggregation using image processing and machine learning. This research will link serotonergic transmission and neuromodulation with sensory perception and behavior.

Institution: Boston University
Career Level: Postdoctoral
Research Summary: My work explores how variations in language modality and exposure can shape language acquisition and use. My research programs have included studying how cochlear implantation at an early age might modulate executive function in adulthood; exploring the neural bases of tactile sign language processing in DeafBlind adults; and currently, studying how the quality of language input from hearing, non-native, signing parents might impact vocabulary acquisition in deaf children. With this diversity supplement award, I aim to identify how hearing parents, as new American Sign Language (ASL) learners, can promote healthy ASL acquisition in their deaf children. This is incredibly important because an overwhelming majority of deaf children in America are born to hearing parents who often do not already know ASL and might even be discouraged from learning it alongside their deaf children.

Institution: University of Washington
Career Level: Predoctoral
Research Summary: My Ph.D. training at the Stone Lab in the Virginia Merrill Bloedel Hearing Research Center, University of Washington, concentrates on understanding the underlying mechanisms of the inner ear, with a focus on the vestibular sensory systems (the balance organs). My research applies genetics and cellular biology to gain insights into the development and regenerative capacities of the vestibular periphery. Understanding development helps me to probe what is required to regenerate these cells and possibly restore function of the system when it fails or degenerates. My Diversity Supplement research project focuses on deleting genes using CreER systems to study ways to promote regeneration of higher numbers and additional subtypes of hair cells. Sensorineural vestibular disorders affect a wide range of people and are an unfortunate side effect of some pharmaceuticals. I am hopeful that the research I am doing will identify new ways to treat vestibular disorders and guide inner ear research to new places.

Institution: Massachusetts Institute of Technology (Diversity Scholar); now at the University of California, Berkeley
Career Level: Predoctoral
Research Summary: Developing devices that can sense, compute, and actuate on the body to cure diseases has always been fascinating to me—seeing how they tangibly help people. Because of this interest, at MIT as an undergrad and master’s degree student, I developed an implantable microphone to enable fully-implantable assistive hearing devices. This project was motivated by the limitations external assistive hearing devices place on the user. Continuing in this vein of research, I have started my Ph.D. at UC Berkeley, where I am developing metamaterial self-assembly methods. This is a fundamental building block in creating new interfaces to the body with materials which can’t exist in nature. With this fabrication method, I hope to develop uniquely-addressable magnetoelectric microrobots that can sense and actuate upon single neurons non-invasively.

Institution: Arizona State University
Career Level: Predoctoral
Research Summary: My research interest involves understanding the neural mechanisms of speech production and speech disorders (e.g., stuttering and apraxia of speech). I work in the Speech and Brain Research Laboratory at Arizona State University. In the proposed project in this supplement, I will examine (1) how the brain prepares the auditory and somatosensory systems during speech planning, and (2) whether sensory preparation during speech is related to speech production or perception accuracy. Findings from this project will serve as a foundation for developing personalized neural treatments for speech disorders. By completing this project, I will gain in-depth experience with electrophysiological signal recording and somatosensory stimulation techniques. Additionally, this project will provide me with the necessary training and preliminary data to apply for an NIH F31 fellowship application.

Institution: MGH Institute of Health Professions and Harvard University
Career Level: Predoctoral
Research Summary: My research interests are centered broadly on child language development and disorders. As a Harvard University Ph.D. student, my research through the MGH Institute of Health Professions focuses on studying developmental language disorder (DLD), a disorder that affects understanding and using language. More specifically, my work aims to understand and improve screening and identification of DLD within educational and clinical settings. The goal of my diversity supplement project is to streamline the process of taking and analyzing language samples, which provide rich information for screening for and diagnosing DLD.

Institution: University of Colorado Boulder
Career Level: Predoctoral
Research Summary: My research project is being conducted in the Children's Auditory Perception Laboratory, where current research focuses on improving hearing health care for children who have developmental disabilities. My project is focused on isolating factors that affect behavioral threshold estimates in young children who have developmental disabilities. Our long-term goal is to improve behavioral methods for evaluating hearing in children with developmental disabilities, ensuring timely identification of hearing loss in this population.

Institution: Harvard Medical School
Career Level: Postbaccalaureate
Research Summary: I am studying the function of the Ms4a receptors in cell signaling. The Ms4a genes serve as receptors for fatty acids in two cell types: olfactory sensory neurons and microglia. To better understand how Ms4a activity affects cell function, I am currently exploring cell signaling pathways downstream of the Ms4as and building assays that ultimately should allow us to identify new ligands for the Ms4as. Our work should shed new light on the function of these mysterious receptors in both the nose and brain.

Institution: University of Michigan – Ann Arbor
Career Level: Research laboratory technician, senior
Research Summary: I graduated with B.S. and M.Sc. degrees from the University of Michigan, and did my M.Sc. research in the Clowney lab. As an M.Sc. student and now research assistant, I am studying the developmental events that wire the learning and memory center of the insect brain.

Institution: University of Pennsylvania Perelman School of Medicine
Career Level: Predoctoral medical student
Research Summary: Bitter taste receptors were originally defined based on their role in bitter taste, but they are also expressed in other tissues throughout the body, including the airway and oral epithelium. These receptors regulate a diverse array of cellular responses including innate immunity, cell proliferation, and metabolism. I am studying how bitter taste receptors regulate epithelial cell function with a goal of identifying novel signaling pathways that intersect with these receptors.

Institution: Northwestern University
Career Level: Predoctoral
Research Summary: I graduated with a B.A. in June 2021 and am planning to pursue a Ph.D. in fall 2023 with the goal of developing early interventions to reduce socioeconomic disparities in children’s academic achievement. My diversity supplement project involves researching language processing in late-talking, English-Spanish bilingual toddlers to improve the early identification of developmental language disorder (DLD) and thus reduce long-term academic, social, and economic impacts on individuals. Most current measures cannot distinguish between delays in accumulated language knowledge and impairments in language learning/processing, the latter being characteristic of DLD. Our longitudinal study will use eye-tracking to compare word recognition and novel word learning for typically developing and late-talking bilingual children at 24 and 30 months to evaluate whether language processing is better at predicting lexical development than vocabulary measures.

Institution: Ohio State University
Career Level: New/junior investigator
Research Summary: The current opioid epidemic and COVID pandemic has resulted in a sharp increase in grandparents raising grandchildren, also known as grandfamilies. My research focuses on understanding the strengths and challenges of grandfamilies in order to create and deliver interventions that build resilience by encouraging self-care, communication, resourcefulness, and empowerment. I am also interested in culturally grounded research and the development of culturally grounded measures and interventions. Some current projects include an assessment of the human service landscape in central Ohio as it relates to grandfamilies; the implementation of a self-care program for grandparents raising grandchildren and for their grandchildren between the ages of 9 and 12; and identifying risk factors for delayed language development in children from low-income families.

Institution: Carnegie Mellon University
Career Level: Predoctoral
Research Summary: I am working towards a Ph.D. in cognitive neuroscience with a focus on auditory neuroscience. My current research project investigates the relationship between auditory selective attention and auditory category learning. We hypothesize that the process of auditory category learning leans on auditory selective attention to direct focus to features of sounds that are most diagnostic of their category membership, making sound categorization more efficient and accurate. This has implications for how humans learn the sounds of a language, as in second-language acquisition. My ultimate research goals are to discover the ways we can take advantage of auditory selective attention to better learn second-language auditory categories to make language learning easier for adults.

Institution: MEMStim, LLC
Career Level: Predoctoral
Research Summary: My current research project involves the manufacture of cochlear implants using 3D printing technology. The existing manufacturing process for cochlear implants requires hand assembling of bundled micro-scale electrode arrays, which is expensive and labor-intensive. A printing manufacturing process allows for flexibility in the design and structure of electrodes. My work at MEMStim involves the optimization of the manufacturing process, and the development of cochlear implants that can be utilized in animal studies.

Research Summary: Laryngotracheal stenosis (LTS) is a rare disease of the upper airways characterized by progressive extrathoracic obstruction leading to devastating dyspnea. Management is primarily surgical and aims at maintaining airway patency. Although adjuvant therapies are employed, they have shown inconsistent efficacy. The lack of effective medical therapy is due, in part, to a limited understanding of the pathogenesis of LTS. My work focuses on understanding the underlying mechanism responsible for initiating and propagating fibrosis in the proximal airway. Specifically, we study the immune, fibroblast, and epithelial profile of LTS patients using advanced technologies such as flow cytometry, single cell sequencing, and multiplex immunofluorescence. My current project investigates the spatial localization of the pathological fibroblast population in the scar tissue of LTS patients using multispectral immunofluorescence.

Institution: New York University
Career Level: Predoctoral
Research Summary: My doctoral research seeks to determine how social signals interact with auditory cortical circuitry to affect sound encoding. Due to the prevalence of social interaction in daily lives of animals in nature, the striking effect the act of social interaction has on brain function, and the multitude of non-sensory signals present in the auditory cortex, this research has the potential to reveal new information about the basic function of the auditory cortex under ethologically relevant conditions. These results will guide future studies in other sensory systems which may receive input from brain areas involved in social interaction, and will provide a framework to understand how communication disorders may be affected by neural dynamics.

Research Summary: Chemosensory perception is highly variable among both individuals and populations. From a public health perspective, I explore how genetics, environment, and disease shape person-to-person variability in taste and smell. My current work is about the effect of inborn genotype on human bitter perception, how air pollution affects the sense of smell, and the prevalence of taste and smell loss as defining symptoms of COVID-19.

Research Summary: Although many studies have indicated that cognitive behavioral therapy (CBT) is an effective treatment for tinnitus, which is characterized by ringing in the ears, far fewer have considered the ways in which various demographics and populations might view that treatment. Our research is attempting to focus on one demographic, veterans, to understand how CBT for tinnitus is perceived and can be improved to meet the needs of that population. Tinnitus is a common service-related health complaint among veterans and can be complicated by a variety of co-occurring issues including traumatic brain injury and post-traumatic stress disorder. It is our hope that by assessing the acceptability of CBT for tinnitus among veterans and non-veterans, we can begin to identify factors that can be changed to better accommodate this unique population’s needs.

Research Summary: I am a research clinician in the Early Intervention Research Group (EIRG) at Northwestern University. Since 2019, I’ve worked as an interventionist and assessor on several federally funded treatment efficacy studies under the direction of Dr. Megan Roberts. Our current research projects aim to support and enhance the early development of infants and toddlers with hearing loss, autism, and/or developmental language disorder.
As both a clinical researcher and licensed speech-language pathologist (SLP), I enjoy empowering caregivers as they support their child’s language, communication, and play development! Additionally, I am passionate about promoting and increasing access to early childhood services—especially in marginalized, vulnerable, and/or underserved communities.

Career Level: New/junior investigator
Research Summary: I am a person who stutters, a speech-language pathologist, and an assistant professor at Duquesne University. My research interests include better understanding and predicting individual differences in the experience of stuttering (stammering), understanding how adverse impacts related to the condition develop, and determining how moments of stuttering occur in speech. I am currently investigating the role cognitive-affective processes play in speech production and language formulation processes in stuttering and non-clinical populations. I also practice clinically and am actively involved in clinical education regarding stuttering assessment and treatment.

Career Level: Predoctoral
Research Summary: For my current predoctoral ventures, I am a graduate research assistant in the labs of Dr. Jeremy McIntyre and Dr. Karina Alvina in the department of neuroscience at the University of Florida. My current research project focuses on the modulating role of the neuropeptide melanin concentrating hormone (MCH) in the olfactory bulb. With the use of electrophysiology, immunohistochemistry, and behavioral studies, I will investigate the contributions of this hypothalamic neuropeptide in modulating responses to olfactory stimuli.

Research Summary: My program of research examines language and literacy in individuals with diverse linguistic backgrounds. Most theoretical models of language and literacy acquisition are largely based on monolingual and hearing populations. Our understanding of neurodevelopment is even more limited, and models do not adequately represent the variability of different populations of learners. This has direct implications for the identification and intervention of reading difficulties and the education of linguistically diverse students. To better inform our understanding, I am motivated to examine children’s cross-linguistic experiences and their influences on brain development for language and reading acquisition. Throughout my research career, I aim to study the reciprocal relations bridging these areas of interest in hearing, deaf, and hard-of-hearing children, and in children with language and reading difficulties.
