Current Gerontology PhD Students

Elizabeth Avent began the doctoral program at the Davis School of Gerontology in Fall 2017. She completed her Bachelor of Arts in Sociology at Georgia State University in 2012, and her Master of Arts in Gerontology at Georgia State University in 2016. Her research interests include elder abuse policy, prevention, and intervention, the experiences of victims of late-life intimate partner violence, how adverse childhood experiences can contribute to lifespan victimization, and improving and developing appropriate services for older IPV victims through community and policy interventions.

During her time at Georgia State University, Liz was a part of the Gerontology Institute’s Convoys of Care Research Team working on a NIH-funded study that focuses on the care networks of residents in assisted living facilities. She has worked at Grady Memorial Hospital in Atlanta, Georgia, assisting with research on improving care transitions of patients being discharged from the hospital. She has also worked at the Georgia Council on Aging, assisting with planning and executing the quarterly meetings of the Coalition of Advocates for Georgia’s Elderly, in which aging issues are selected to advocate to policymakers.

Liz works in Dr. Wilber’s Secure Old Age Lab.

Shelby Bachman is a doctoral student in the USC Leonard Davis School of Gerontology working under the direction of Dr. Mara Mather. Shelby’s research is focused on how emotional arousal affects the brain and cognition across the lifespan. In particular, she is interested in how the locus coeruleus-norepinephrine system changes across the lifespan and the consequences of those changes for memory performance, attention, brain structure, and brain function. She uses behavioral, psychophysiological, and neuroimaging methods to investigate these questions. Prior to her doctoral studies, Shelby completed a Master of Science at the Berlin School of Mind and Brain and a Bachelor of Science in Neuroscience at USC.

Valeria Cardenas is a doctoral student at the Leonard Davis School of Gerontology. She received her Bachelor of Arts in Social Welfare and Justice, and Public Relations from Marquette University; and a Master’s in Aging Services Management from the University of Southern California. Valeria’s research interests are in palliative care and hospice care for the Latino community. She is currently working with Dr. Susan Enguidanos.

Yonashiro-Cho-HeadshotA graduate of USC in Biological Sciences and Gerontology, Jeanine Yonashiro-Cho returned to USC to begin her doctoral studies in Fall 2013. Her research interests focus on improving and preserving the health and well-being of older adults with a particular focus on reducing health disparities and protecting vulnerable elders.

Before returning to California, Jeanine served as the State of Hawaii’s Planner for Aging Services where she worked to strengthen Hawaii’s aging services infrastructure and development of evidence-based health promotion and disease prevention programs for older adults.

Working under the direction of Dr. Kathleen Wilber, Jeanine is currently studying forensic markers of elder abuse and promising elder abuse interventions, such as the Elder Abuse Forensic Center model.

Eunyoung Choi is a Ph.D. student at the Leonard Davis School of Gerontology. She received her Bachelor of Arts in Psychology from Yonsei University in 2015 and her Master of Arts in Gerontology at Kyung Hee University in 2018.

She is also interested in older adults’ technology use to better manage their health and lifestyle. During her master, Eunyoung worked as a research assistant on the nationally funded project “The Development of Dementia Literacy Intervention Program”, aimed at developing a mobile-based intervention program to increase the dementia literacy levels of older Korean adults. She also has prior work experience at the Samsung-ro Nursing Care in South Korea, assisting with implementing intervention programs for cognitively declined older adults to maintain their functions and delay further progression.

stephen_frochen150x150Stephen Frochen is a doctoral candidate and Ruth L. Kirschstein fellow at the Leonard Davis School of Gerontology at the University of Southern California. Frochen’s research interests include housing for the elderly, particularly senior housing. He has conducted extensive research on residential care in the City and County of Los Angeles as well as all of California. His most recent research focuses on a new eldercare land use ordinance in Los Angeles, which streamlines the permitting process of eldercare facility developments and allows them to be sited in any area of the jurisdiction. He is currently working on understanding and demonstrating how land use and planning tools such as this new eldercare ordinance may help to close the gap between an already burgeoning demand for residential and institutional care among older adults and a languishing supply of such services and facilities.

gerson_galdamez150x150Gerson Galdamez is a first year doctoral student at the Davis School of Gerontology. He completed his undergraduate degree in Human Aging and Development at USC in 2016, during which his research focused on economic security in late life among Latino immigrant groups. This research primarily involved detecting income dynamics across the lifecourse, and how these dynamics vary by citizenship and ethnicity.

Gerson’s work in the Secure Old Age lab focuses on Latino economic security and elder abuse. He engages in projects focused on the effectiveness of elder abuse interventions, and hopes to develop further research on legal and criminological aspects of elder abuse.

Haley Gallo is a doctoral student at the Davis School of Gerontology. She received her Bachelor of Science in Psychobiology, with a minor in Gerontology, from the University of California, Los Angeles in 2017.

Yuang_Zhang(resized)Yuan Zhang is a doctoral candidate in Gerontology. She came to USC with an MS in Survey Methodology from the University of Michigan and a BA in Economics from the Central University of Finance and Economics. Her overarching research objective is to understand the role of behavioral, social, environmental, and contextual factors in making the aging process different across time and place. Her research covers multiple topics in demography and population health, focusing on determinants of morbidity, disability, and mortality over the life course in both less developed and more developed settings. Her dissertation work uses data from the China Health and Retirement Longitudinal Study, a nationally representative study of middle-aged and older Chinese, to assess age-related physiological changes that underlie the risk of disease, disability, and mortality, and study the determinants of physiological health change and mortality among the older Chinese. In addition to her dissertation research, she is involved in research on life expectancy and extension of healthy life.

Joshua_Kramer_headshotI enjoy hiking, biking, and exploring new and unusual places and experiences. I also am somewhat of a technophile. My research interests include stem cell maintenance and management of homeostasis during periods of persistent stress. I also want to examine the genetic pathways that are most perturbed during aging in such a system and how to remedy these effects.

KennethKenneth is a doctoral student in USC Leonard Davis School of Gerontology’s Biology of Aging program. He earned his Bachelor’s degree in Molecular and Cell Biology, with an emphasis in Genetics, Genomics, and Development, from the University of California, Berkeley in 2011.  He then attended Dominican University of California and earned his Master’s degree in the Biological Sciences in 2014. Throughout his Master’s education he worked in the Kapahi Lab at the Buck Institute for Research on Aging in his hometown of Novato, CA, where he studied the effects of the gut microbiome on responses to dietary restriction, the genetic mechanisms behind gut integrity, and the role of natural genetic variation in response to dietary conditions.
Kenneth’s research interests, as well as his intended doctoral research, are to continue his work on genetic variations and how they modulate dietary response in relation to the aging process.
