Teal Eich, Lab Director
Teal is an Associate Professor of Gerontology and Psychology, and the Associate Dean of the Art and Healthy Aging (AHA) Center. Her research centers on understanding sex differences in the cognitive and neural mechanisms underlying learning and memory changes in healthy and pathological aging, with a particular focus on Alzheimer’s disease. She uses behavioral and neuroimaging (structural- and functional-MRI) methods to probe these interactions in healthy younger and older adults, and in individuals at risk for developing neurologic disorders including Alzheimer’s Disease based on biologic and genetic risk factors.

Lorena Ferguson, Postdoctoral Fellow
Lorena received her PhD in Cognitive Neuroscience from Rice University, where she examined how individual differences in aging impacted emotional memory and neurobiological function. In the Lifespan Cognition Lab, she researches how sex differences and mental health in late life influence memory and neurobiology. She has a particular focus on the hippocampus and the locus coeruleus, two brain regions that are important for memory and are affected by Alzheimer’s pathology early in disease progression. This combination of high-resolution MRI and age-sensitive behavioral measures allows for early detection of memory perturbations in aging that may be indicative of dementia risk.


KJ Davidson-Turner, Postdoctoral Fellow
KJ Davidson-Turner is a postdoctoral scholar at the University of Southern California. She draws upon both biological and sociological perspectives to better understand health disparities and age-related diseases at a population-level. Specifically, her research focuses on how stress and other social factors impact women’s hormonal health, aging transitions, and later life health outcomes. Prior to USC, KJ received her B.A. in Neuroscience from Middlebury College and her PhD in Sociology and Demography from the University of Texas at Austin.


Joan Jimenez-Balado, PhD, Collaborator
Joan is a cognitive and computational neuroscientist interested in studying the vascular contribution to the aging brain. He started his career doing a Ph.D. in Neuroscience at the Vall d’Hebron Hospital (Neurovascular, Barcelona), where he explored how cerebral small vessel disease affects cognition. He then did a first postdoctoral fellowship at the Lifespan cognition lab (University of Southern California, Los Angeles), trying to disentangle how complex mappings of cerebrovascular lesions correlate to specific clinical phenotypes. He then moved to the Institut d’Investigacions Mèdiques Hospital del Mar (Neurovascular, Barcelona), where he is currently integrating multi-modal data (genetics and neuroimaging) to improve the prediction, understanding and prognosis of cerebrovascular diseases.

Jessie (Chih-Yuan) Chien, Graduate Student
Jessie is a PhD student in the Davis School of Gerontology. She is currently investigating the underlying cognitive mechanisms of age-related differences in memory specificity, such as how memorial interference due to similarity can be reduced via inhibitory mechanisms. In the next steps, she aims to study the potential role of memory specificity in valued-based decision making using both behavioral and neuroimaging methods.
Before coming to USC, she received her M.A. in Psychology from Brandeis University (Master’s thesis advisor: Dr. Angela Gutchess) and a B.S. in Psychology from Penn State University.

Dokyung Yoon, Graduate Student
Dokyung is a PhD student at the Leonard Davis School of Gerontology. She is currently investigating how social and biological factors shape cognitive aging. Her research examines the impact of social isolation, exploring how different patterns of isolation relate to specific domains of cognition. She also studies biological influences, focusing on sex hormone changes during the menopausal transition. By integrating these perspectives, her work aims to reveal how social and biological factors interact to influence cognition in midlife and older women.
Dokyung received her M.A. in Child and Family Studies at Yonsei University and a B.A. in Psychology and a B.S. in Child and Family Studies from Yonsei University.

Gloria Cheng, Graduate Student
Gloria is a PhD student at the Leonard Davis School of Gerontology. Her research interests center on age-related changes in memory and cognition, with an emphasis on identifying early neural and behavioral markers of Alzheimer’s Disease.
Before joining the Lifespan Cognition Lab, she earned her B.S. in Cognitive Sciences at the University of California, Irvine, and later worked as a research coordinator in the Stanford Memory Lab.


Suhani Amin, Graduate Student
Suhani is a PhD student in the Neuroscience Graduate Program. Her research uses structural and functional MRI to investigate risk factors for dementia and cognitive decline, with a focus on how individual findings inform a population-level understanding of brain health. She is additionally co-mentored by Eleanor Hayes-Larson. Before joining USC, Suhani received a B.S. in Behavioral Neuroscience from Northeastern University.


Anya Vincent, Study Coordinator
Anya is the current study coordinator for the SAGE Study. She is interested in the relationship between the brain, hormones, and aging and how those affect cognition. Before joining the lab, she completed her M.S. in Gerontology and B.S. in Neuroscience both from USC.


Rahul Naveen, Undergraduate Research Assistant
Rahul is a B.S. Neuroscience major and Spanish minor at the University of Southern California. He is a research assistant in the Lifespan Cognition Lab, where he contributes to ongoing work examining cognitive aging and memory function. He is particularly interested in the relationship between aging, hormones, and memory, and how these factors interact in the development of neurodegenerative diseases. His goal is to better understand the biological mechanisms underlying age-related cognitive decline and to support efforts aimed at early detection and intervention. Outside of his academic work, Rahul is an EMT, volunteers in the emergency room, participates in street medicine efforts, and helps provide blood pressure and A1C screenings to underprivileged communities across Los Angeles. Long-term, he plans to integrate these experiences with a career in medicine to support patients through both scientific discovery and clinical care.


Blanca Diaz, Research Assistant
Blanca in a recent graduate from the University of Southern California, where she majored in Health and Human Sciences and minored in Cultural Competence in Medicine. Her interest in partaking in research with The Lifespan Cognition Lab stems from her volunteer experience with Adventist Health Hospice where she became more cognizant of the sex differences associated with Alzheimer’s disease. That said, Blanca intends to become a physician, and she aims to continue to further her understanding of the needs of older adults to ultimately improve their overall health and well-being.


Ryan Kober, Undergraduate Research Assistant
Ryan is a senior at the University of Southern California, majoring in Human Development and Aging on the Health Science track and beginning his Master of Arts in Medical Gerontology through USC’s Progressive Degree Program. As a pre-medical student, he is interested in how biological and social factors influence health outcomes across the lifespan, with a focus on aging and cognitive change. Beyond academics, Ryan is committed to service and leadership as president of the American Red Cross at USC, where he organizes campus-wide humanitarian and health initiatives. He is eager to apply his background in healthcare training and community engagement to research in lifespan development and cognition.


Megan Pham, Undergraduate Research Assistant
Megan is a senior at the University of Southern California majoring in Neuroscience and minoring in Occupational Sciences. She is interested in the intersection of cognitive science, aging, and healthcare. Her goal is to pursue a career in medicine and become a physician. Her research position with the Lifespan Cognition Lab and interning at Lakeside Community Healthcare has furthered her passion for improving patient outcomes within the aging population.
