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.


Nicole Armstrong

Nicole Armstrong, PhD, is a postdoctoral fellow in the Laboratory of Behavioral Neuroscience at the National Institute on Aging (NIA) and is mentored by NIA senior investigator Susan Resnick and Cochlear Center director Frank Lin. She received her PhD in epidemiology from Johns Hopkins Bloomberg School of Public Health in 2017. Her interests are in cognitive aging, and mechanisms underlying the associations of risk factors, such as sensory loss, with cognitive decline and dementia.


Michael Yong

Michael Yong, MD, is a resident physician in Otolaryngology-Head and Neck Surgery at Johns Hopkins University School of Medicine from the University of British Columbia. Through the support of the Clinician Investigator Program research fellowship, funded by the Royal College of Physicians and Surgeons of Canada, he is pursuing the Master of Public Health/Master of Business Administration dual degree at Johns Hopkins University. His research interests include pediatric and age-related hearing loss, health interventions in underserved communities and cost-efficiency analyses of health systems.


PRE-doctoral trainees

Alexander Kim

Alexander Kim, MTM, is a medical student taking a research year at the Cochlear Center in between his third and fourth year of medical school. He completed his undergraduate degree in public health and immunology at UC Berkeley, and a master’s degree in translational medicine at UCSF/Berkeley. His current research focuses on behavioral interventions for hearing loss, and he plans on applying for residency positions in otolaryngology in the fall of 2020..

Haley Heng-Yu Lin

Haley Heng-Yu Lin, MD, received her Doctor of Medicine degree from National Yang-Ming University in Taiwan and hope to become an otolaryngologist in the future. She is a current Master of Public Health student at Johns Hopkins Bloomberg School of Public Health and is interested in patient-physician communication in hearing loss population and the health/financial/social impacts on the aging society given the significant health care burden resulted from age-related hearing loss..

Junghyun Park

Junghyun Park, MSW, is a Ph.D. student at the New York University Silver School of Social Work. His overall research program is to identify health disparities among the Deaf and hard of hearing (D/HH) population and older adults with hearing loss (HL). His current research aims to examine the mechanisms of the risk factors and protective factors affecting the association between HL and cognitive health among older adults, within a bio-psycho-social environmental context. Ultimately, he hopes to develop and implement effective mental and cognitive health promotion interventions that are culturally tailored to the real needs of the D/HH population and older adults with HL. .

Alison Huang

Alison Huang 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..
