POST-doctoral trainees

Anna Marie Jilla

Anna Marie Jilla, PhD, AuD, is a postdoctoral fellow in the Department of Epidemiology and is mentored by Cochlear Center director Frank Lin, and core faculty Amber Willink, Nicholas Reed, and Jennifer Deal. She received her AuD and PhD from the University of Oklahoma Health Sciences Center in 2017 and 2019, respectively. Her research interests include applications of health economics for improving hearing health care accessibility and shaping health policy for adults with hearing impairment.


PRE-doctoral trainees

Julie Yi

Julie Yi is a medical student taking a research year at the Cochlear Center for Hearing and Public Health between her third and fourth years of medical school. She completed her undergraduate degree in chemistry at Duke University and worked in healthcare consulting prior to medical school. Her research focus is on behavioral interventions for age-related hearing loss, and she plans to apply for residency in otolaryngology in the fall of 2021..

Lama Assi, MD

Lama Assi, MD, is currently an MPH student at the Johns Hopkins Bloomberg School of Public Health. She received her medical degree from the American University of Beirut in Lebanon and completed a postdoctoral research fellowship with Dr. Bonnielin Swenor at the Dana Center for Preventive Ophthalmology, Wilmer Eye Institute, during which she collaborated with Dr. Nicholas Reed on projects related to sensory loss and health care utilization. After completing the MPH program, she hopes to complete clinical training in ophthalmology and later work as a clinician-researcher focused on improving access to care for older adults with sensory loss.

Anna Javins

Anna Javins is the 2020-2021 audiology doctoral resident in the Johns Hopkins Department of Otolaryngology in the Johns Hopkins Outpatient Center. Anna received her undergraduate bachelor of arts degree in speech and hearing science from The Ohio State University and will receive her doctorate of audiology (Au.D.) from Vanderbilt University School of Medicine in May 2021.   Anna completed an undergraduate honors research thesis exploring the impacts of cognitive workload, situational awareness, and hearing loss on driving behaviors in both young and older drivers. In medical school, she spent time doing research regarding directional microphone configurations and spatial awareness as it relates to hearing aid use. She has also developed a special passion for vestibular research and completed her doctoral capstone on a novel acoustic vestibular evoked myogenic potential (VEMP) measure of the vestibulospinal pathway to assess postural instability in dizzy patients. Anna’s research passions revolve around healthy balance and hearing during the aging process as well as disparities in health literacy among geriatric and minority populations. Anna aims to publish research that helps to empower patients to take ownership of their healthcare while actively dismantling barriers to this goal. .

John Shin

John Shin is a SHARP fellow at the Cochlear Center for Hearing and Public Health. Before arriving at the Center, John spent the two years at the National Institute on aging as a post-baccalaureate Intramural Research Training Award Fellow in Dr. Susan Resnick's lab. Working with his mentor, Dr. Murat Bilgel, he implemented a retrospective study design looking at the associations between amyloid, brain atrophy, and cognition in the Baltimore Longitudinal Study of Aging.   John received his bachelor of science degree in neuroscience from Johns Hopkins University in 2018 and is currently pursuing a master of public health degree with a concentration in epidemiological and biostatistical methods for public health and clinical research at the Johns Hopkins School of Public Health.

Alison Huang

Alison Huang, MPH, is a PhD student in the Department of Mental Health. She is interested in modifiable risk factors of age-related cognitive decline and poor mental health in older adults. She also works with the Cochlear Center studying mental health outcomes, such as loneliness and social isolation, associated with hearing impairment. Prior to coming to Hopkins, she worked for several years in social behavioral research consulting. She currently holds a MPH and a Certificate in Survey Methodology. Her mentors are George Rebok, Jennifer Deal, and Frank Lin..

Pei-Lun Kuo

Perry Kuo is a physician from Taiwan and currently a PhD student in Epidemiology with a focus on aging at Johns Hopkins Bloomberg School of Public Health. His research interests include investigating potential modifiable risk factors for age-related hearing loss, evaluating the effect of hearing loss on physical activity and physical functions and assessing the impact of hearing aids on physical activities and physical functions.

Pablo Martinez Amezcua

Pablo Martinez Amezcua, MD, received his medical degree from the National Autonomous University of Mexico and is a doctoral student in the Department of Epidemiology at Johns Hopkins Bloomberg School of Public Health. He is interested in studying social determinants of health, physical activity and prevention of diseases associated with age such as hearing loss, cardiovascular disease and mobility disability.

Danielle Powell

Danielle Powell, AuD, is a doctoral student in Epidemiology at the Johns Hopkins Bloomberg School of Public Health. Prior to starting the program, she worked as an audiologist in the Washington, D.C., area. She received her Doctorate of Audiology from the University of North Carolina in 2013. Her research interests include the association of hearing loss with dementia, and healthy aging..

Jonathan J. Suen

Jonathan J. Suen, AuD, is currently a PhD student at the Johns Hopkins School of Nursing (JHSON) where his research focuses on examining the relationship between age-related hearing loss and loneliness. Following his clinical studies in audiology at Gallaudet University, he completed a postdoctoral fellowship with Dr. Frank Lin where he addressed hearing loss within public health frameworks. Through his participation at the JHSON's Center for Innovative Care in Aging during the fellowship, he developed an interest in gerontology and behavioral interventions for promoting hearing health equity and healthy aging. He is currently co-advised by Dr. Jennifer Wenzel of the JHSON and Dr. Frank Lin for his PhD training..
