Gillian Fennell

Gillian Fennell is a fifth year PhD candidate at the Leonard Davis School of Gerontology under the mentorship of Dr. Jennifer Ailshire and Dr. Elizabeth Zelinski. She began her academic career at USC in 2019 after completing a bachelor’s degree in Human Development at Cornell University. Her doctoral studies focus primarily on how older adults with chronic pain subjectively perceive their futures–namely, their perceived chances of retirement and death at certain ages. In studying the imagined futures of individuals with chronic pain, she offers insight into this large subpopulation’s likelihood to adequately plan for advanced ages.

Alice J. Kim

Alice Kim is a Clinical Science PhD student at USC Dornsife working under the mentorship of Dr. Christopher Beam in the Lifespan Development and Clinical Aging Lab. Her work is focused on using developmental behavior genetics to understand how psychosocial experiences and genotype contribute to individual differences in cognitive aging and risk of ADRD. Alice graduated from Cornell University with a Bachelor of Arts in Psychology and Sociology.

Margarita Osuna

Margarita Osuna is a PhD student in Gerontology at the University of Southern California. Under the mentorship of Jennifer Ailshire, she is conducting research in the Ailshire Lab focused on Latin American demography, health, and aging. She is interested in socioeconomic inequalities in health and well-being in the older adult population. Margarita graduated from Pontificia Universidad Javeriana in 2015 with an undergraduate degree in Sociology and is currently a member of the LAHA research group (Latin America Health and Aging research group).

Ana Silverstein

Ana Silverstein is a Molecular Biology PhD student working under the mentorship of Dr. Pinchas Cohen at the USC Leonard Davis School of Gerontology. Ana’s work primarily focuses on the interface between mitochondrial genetics, mitochondrial malfunction, and immune system decline in aging populations. Her research looks to explore the role of mitochondrial-derived peptides in modulating immune system communication, to better elucidate the key contributors to age-related immune system decline and chronic systemic inflammation.

Kristina Dang


Calley Fisk

Calley E. Fisk, PhD, received her doctorate in Sociology from the University of South Carolina. She examines the embeddedness of structural racism in the social, economic, and built environments of U.S. neighborhoods and the resulting impacts on wellbeing for older Black and White adults. Her most recent projects focus on the relationship between historical redlining and various aging related health outcomes, such as cognitive functioning and biological markers of advanced aging.

Eric T. Klopack

Eric T. Klopack, PhD, is a postdoctoral researcher in the Leonard Davis School of Gerontology at USC. He received his doctorate in Sociology from the University of Georgia. His research focuses on the processes by which social circumstances and relationships interact with biological and developmental systems to produce inequalities in illness, aging, and mortality. He current research investigates how life experiences (especially early life adversity and social stressors) influence immunological aging and biological hallmarks of aging that may lead to impaired cognitive functioning, risk of Alzheimer’s disease and related dementias (ADRD), chronic disease morbidity, and mortality.

Aaron Lim, PhD

Aaron Lim, PhD, received his doctorate in clinical psychology from the University of California Los Angeles. His research interests include longitudinal predictors of financial exploitation vulnerability, health disparities in cognitive aging, and the effects of substance use on decision-making in older adults.

Addam Reynolds

Addam Reynolds, PhD, received his doctorate in social work from Rutgers University-New Brunswick. His research interests include understanding how intersecting social positions in childhood contribute to later life health and well-being. He is also interested in how social conditions get under the skin to contribute to disease and mortality among older adults. He is currently investigating how intersecting social positions (i.e., socioeconomic status, race and region) contribute to later life cognition and immunological functioning.
