Former Trainees: What they are doing now

Dr. Bernie Lohr

Current Position: Associate Professor, Department of Biological Sciences, University of Maryland Baltimore County

Research in the Lohr Lab focuses on the auditory physiology and sensory biology of songbird acoustic communication. Dr. Lohr is interested in understanding the relationship between the production and perception of communication signals in the context of their mechanism, development, function, and evolution. Researchers at the Lohr Lab take an integrative approach that draws on methods from behavioral ecology, comparative psychology, neurophysiology, and evolutionary biology to investigate fundamental questions in animal communication.


Kelsey Dutta is a graduate student working with Drs. Shihab Shamma in the Neural Systems Lab. She previously worked on neuroanatomy and electrical stimulation projects in the auditory midbrain while earning undergraduate degrees at the University of Connecticut. Her work at NSL will focus on signal processing and physiology in auditory and associated cortices.

Dr. Jonathan Simon

Current Position: Professor, Department of Electrical and Computer Engineering and Department of Biology, University of Maryland

Dr. Simon's broad research goal is to understand how the auditory cortex processes complex sounds such as speech and other natural sounds. Because of the focus on speech and higher order processing, his research uses human rather than animal subjects. To non-invasively record and analyze real-time neural processing in humans, Dr. Simon's uses magnetoencephalography (MEG), because of its high temporal resolution (milliseconds) and reasonable spatial resolution (millimeters). Dr. Simon is now a C-CEBH faculty member and director of his own lab, the Computational Sensorimotor Systems Lab.

Dr. Brittany Jaekel

Current Position: Research Scientist at Starkey Hearing Technologies in Eden Prairie, MN

Dr. Jaekel’s work guides the newest technology in hearing aids, with a focus on the listener’s experiences understanding speech in noise and the cognitive effort used to understand that speech. She earned her PhD in Hearing and Speech Sciences from the University of Maryland in 2020 (co-mentors: Matt Goupell and Rochelle Newman), as well as a graduate certificate in Measurement, Statistics, and Evaluation. Her dissertation investigated the ability of users of cochlear implants to perceptually restore noisy speech signals, and the extent to which this process was impacted by device- vs. listener-related factors. Dr. Jaekel received funding for this project via an F31 grant from the NIDCD as well as the funding provided by CEBH.

Dr. Kelly King

Current Position: Clinical Research Audiologist in the Audiology Unit at the National Institute on Deafness and Other Communication Disorders, NIH

Dr. King recently wrote: "CCEBH played an integral role in funding a portion of my PhD work, and in advancing my training in the areas of acoustics and the biological processes of hearing. Participating in the program was one of the most rewarding aspects of my graduate education.” Dr. King's primary research interests are in the pathogenesis and manifestations of hereditary hearing and balance disorders, and the correlation of distinctive auditory and vestibular phenotypes with underlying molecular genotypes.


Current Position: Postdoctoral Research Fellow, Heller lab, Stanford University

Maggie Matern defended her PhD in 2019 in the Human Genetics and Genomic Medicine Ph.D. program at the University of Maryland, in the laboratory of Dr. Ronna Hertzano. The main focus of her research was the characterization of transcription factor signalling cascades that occur during cochlear development using a combination of bioinformatic and molecular techniques, as well as using both mice and zebrafish as animal models. Here research interests are understanding how hair cells normally develop, survive, and function in the inner ear.

Dr. Nora Prior

Current Position: Senior research associate in the Psychology Department at Cornell University.

Nora Prior was a postdoctoral fellow working with Drs Gregory Ball and Robert Dooling in the Department of Psychology, examining the role of sound in social interactions with conspecifics. Repeated social interactions with familiar individuals provide the basis for the development of social relationships. The diversity that exists in the phenotypes of social relationships, reflects the varied patterns of social interactions and the contexts in which these interactions occur. Understanding the diversity in social relationships, their etiologies and  varied effects on individuals’ brain and behavior is a fundamental goal of biology and psychology. Deepening our understanding of diverse social relationships will have unforetold impacts on approaches to individual and community health in humans.

Dr. Maureen Shader

Current Position: Assistant Professor in the Department of Speech, Language, and Hearing Sciences at Purdue University.

Maureen Shader received her Au.D. degree from Gallaudet U. in 2013, and completed her Ph.D. degree in Hearing and Speech Sciences (HESP) at UMD in 2019, with co-mentors Matt Goupell and Sandra Gordon-Salant. Her Ph.D. investigated age-related differences in speech perception by cochlear-implant listeners, including the effect of CI stimulation rate and temporal-envelope modulate rate on sentence recognition. Maureen received F32 support from NIDCD during the final phase of her dissertation. She then carried out post-doctoral research fellow at the Bionics Institute in Melbourne, working with Prof Colette McKay. 

Dr. Jenny Boughman

Current Position: Professor, Zoology, Ecology, Evolutionary Biology & Behavior, BEACON Center for the Study of Evolution in Action, Michigan State University.

Does sexual selection cause speciation? This long-standing but controversial question is receiving a lot of attention currently, partly because of the special role that mate choice can play in determining gene flow. Sexual selection is thought to cause reproductive isolation when male mating signals and female preferences diversify because that can lead to sexual isolation among populations. Work at the Boughman Lab investigates behavioral and ecological causes of divergence in mating traits, the genetic basis of traits involved in sexual isolation, and are using a comparative approach to evaluate the generality of early results from model systems. This highly integrative and multilevel approach has proven powerful for uncovering the processes guiding the evolution of behavior and the processes of speciation.

Dr. Micheal L. Dent

Current Position: Professor, Psychology, University at Buffalo, SUNY, Buffalo, NY 14260

Dr. Dent directs the Comparative Bioacoustics Laboratory (Dent Lab). The overall goal of the research in the Dent Lab is to investigate acoustic communication in animals. Researchers take a comparative approach, measuring hearing and vocalizations in a number of different species, including birds and mice. They carry out psychoacoustic studies of hearing in animals using operant conditioning techniques, and record sonic and ultrasonic vocalizations from their subjects in various contexts.

Dr. Grace Capshaw

Current Position: Postdoctoral researcher at Johns Hopkins University, Baltimore MD.

Grace Capshaw’s received her PhD in 2021 from the Behavior, Ecology, Evolution, and Systematics program at the University of Maryland, working with Dr. Catherine Carr. Her research investigated structural variation, physiological function, and evolutionary adaptation of the inner ear in lungless salamander species.

Allie Johnson

Allie is a PhD student working in Jan Edwards’ Learning to Talk lab. She earned my MS in Speech Pathology from the University of Wisconsin-Madison in 2016. Her work is driven by my clinical experiences, and my research agenda requires a translational approach between the lab and the clinic. Her interests are in how young children learn speech and language when their auditory input is compromised due to signal degradation. Primary goals are to: 1) better understand the unique perceptual constraints imposed by cochlear implants; 2) relate specific auditory processing limitations to patterns observed during speech acquisition; and 3) propose new approaches to speech-language intervention to better serve this unique population of children. Allie is also interested in developing more comprehensive speech assessment tools to supplement transcription in the lab and in the clinic.
