Shelby Bachman

Shelby Bachman is a doctoral student at the USC Leonard Davis School of Gerontology, where she works under the supervision of Dr. Mara Mather in the Emotion and Cognition Lab. Shelby’s research is focused on the role of the locus coeruleus, a small brainstem nucleus which serves as the brain’s primary source of norepinephrine, across the adult lifespan. She uses behavioral, psychophysiological, and neuroimaging methods to understand how both structure and function of the locus coeruleus relate to cognition, brain structure and function, and stress reactivity in younger and older adults.

Vale Cardenas

Vale Cardenas received her Bachelor of Arts in Social Welfare and Justice, and a Bachelor of Arts in Public Relations from Marquette University; and a Master’s in Aging Services Management from the University of Southern California. As a doctoral student at the USC Leonard Davis School of Gerontology, she works under the supervision of Dr. Susan Enguidanos in the Enguidanos Lab. Vale’s research focus on seriously ill Hispanic and undocumented populations and their healthcare experiences. She has researched the disparities seriously ill Hispanics face at the end of life.

Haley Gallo

Haley Gallo received her Bachelor of Science degree in Psychobiology with a minor in Gerontology from the University of California, Los Angeles. As a Gerontology doctoral student in Dr. Kate Wilber’s Secure Old Age Lab, Haley’s research focuses on policies that promote the goals of the Age-Friendly Cities and Communities initiative. She is especially interested in the Age-Friendly domains that relate to civic participation and social inclusion. Her research focuses on using co-production to include older adults as researchers in projects that inform local policies. She is passionate about including older adults—particularly those from groups who are traditionally left out—in the development of research and policy that affects people of all ages.


Brendan Miller

Brendan Miller is a Neuroscience Graduate Program PhD student at the USC Leonard Davis School of Gerontology. Miller studies mitochondrial genetics, neurodegeneration, and mitochondrial-derived peptides in the Cohen lab. His research interests include identifying the effect of mitochondrial single nucleotide polymorphisms on novel mitochondrial-derived peptides in Alzheimer’s disease and Parkinson’s disease.

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.

Current Postdocs

Theresa Andrasfay, PhD

Theresa Andrasfay, PhD, received her doctorate in Demography from Princeton University. Her research broadly focuses on population health and the social determinants of health and mortality. She is also interested in assessing methodological tools used to study health and wellbeing. Her recent projects have assessed the association between physical functioning and mortality among older adults and how this relationship varies by race and ethnicity. Her current research examines occupational stratification as a contributor to inequality in health at older ages.

Matthew (Mateo) Farina, PhD

Mateo Farina, PhD, received his doctorate from the University of Texas at Austin. His research interests include life course origins of dementia risk, examining black-white disparities in health, assess in health life expectancies across demographic and geographic groups, and has recently completed some work on disease trends.

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.

Nicholas Resciniti, PhD

Nicholas Resciniti, PhD, received his doctorate in Epidemiology from the University of
South Carolina. His research interest generally includes understanding factors
associated with physical and cognitive aging, with an emphasis on risk factors causing
microbiome disruption (dysbiosis) and how those factors are associated with aging-
related physical and cognitive dysfunction. His current projects include utilizing
dysbiosis-related markers to understanding the longitudinal association and causal
pathways with cognitive function, mild cognitive impairment, and dementia.
