Erin Sundermann, PhD
UCSD Mentors: Mark Bondi, PhD & David Moore, PhD
Dr. Sundermann is a cognitive neuroscientist in the Department of Psychiatry at UC San Diego. Her graduate training started at UCSD in a Psychology Master's program where she conducted research focused on olfactory function as an early indicator of incipient dementia. She then went on to the University of Illinois at Chicago for her doctoral degree in cognitive neuroscience and a postdoctoral fellowship at Albert Einstein College of Medicine in NYC. During her doctoral training, her research program with Dr. Pauline Maki focused on estrogen-related genetic polymorphisms and their association with cognition and brain function in healthy populations and women with HIV. She was fortunate enough to have her doctoral work funded by a Scholar's Grant from the Mount Sinai Institute of NeuroAIDS Disparities (MSINAID) which also involved six weeks of didactic training in NeuroAIDS disparities in NYC. In her postdoc position, Dr. Sundermann worked with the Einstein Aging Study in the investigation of biomarkers and risk factors for cognitive aging and dementia, particularly sex-specific and genetic risk factors.
Dr. Sundermann returned to UCSD as an Assistant Project Scientist in October of 2016. She currently works with Dr. Mark Bondi in cognitive aging and Alzheimer's disease (AD) research and with Dr. David Moore in NeuroAIDS research at the HIV Neurocognitive Research Center. Her current research focus with Dr. Bondi is the application of empirical, neuropsychological methods to more accurately diagnose mild cognitive impairment and "preclinical" AD in nondemented older adults. Dr. Sundermann aims to extend some of these empirical, neuropsychological methods to HIV populations in order to tease apart HIV-infected individuals that are in the AD trajectory from those with HIV-associated neurocognitive impairment.

Dr. Sabbag is a geriatric psychiatrist working as an Assistant Professor at the Department of Behavioral Sciences of the University of Miami – Leonard Miller School of Medicine, who is board certified in both adult and geriatric psychiatry. He received his medical degree from Universidad del Norte in Colombia and did his psychiatry residency and geriatric psychiatry fellowship at the University of Miami. Dr. Sabbag is currently involved in clinical, research, and educational endeavors. His clinical duties encompass the evaluation and management of older adults in the outpatient and inpatient settings, treating patients of various ethnicities, socioeconomic status, gender diversity, and with diverse mental and medical illnesses, including HIV. Dr. Sabbag performs comprehensive memory disorder evaluations and participates in multidisciplinary staffing conferences to determine patient diagnoses and treatments in neurodegenerative diseases.
His research interest involves the geriatric population, specifically in the area of functionality, and in the development of strategies that will enable older adults, especially those at risk such as ethnic minorities, cognitively impaired and HIV positive populations, to live independently in the community. He has worked in research involving older ethnically diverse LGBT adults, and in assessments of cognitive and functional capacity of adult patients with severe mental illness, HIV and cognitive impairments, through the use of technology. The main focus of his research has been on Hispanic geriatric populations, the LGBT community, HIV populations, and the effect that these may have in functional and cognitive impairment. He has published various papers and book chapters, and presented findings from his research at important national and international meetings. He participates as Co-PI in dementia trials, both conducted by pharmaceutical industries and sponsored by the NIMH. He is also involved in education at the psychiatry residency training program and the University of Miami Medical School, where he dedicates part of his time as the Associate Program Director for the psychiatry residency program, Clerkship Director of third year medical students rotating through psychiatry, director of the Gender, Sexual Health and Orientation medical student special interest pathway, and faculty advisor for the medical student psychiatry interest group and academic societies.
Elizabeth Vásquez, DrPH, MPH
Home Mentors: Deborah Gustafson, PhD & Eli Rosenberg, PhD
Elizabeth Vásquez is an Associate Professor at the University at Albany School of Public Health, Department of Epidemiology and Biostatistics. She earned her MPH from Columbia University Mailman School of Public Health and her Dr.PH. from New York Medical College, School of Public Health. Her research interest in studying physical activity and health disparities evolved from her research experience seeing its influence on older adults diagnosed with arthritis and osteoporosis. These experiences have profoundly shaped her research questions and have shaped her passion for understanding the health of aging populations. Her professional transition to studying older people living with HIV began with her observations that research on these populations was scant and not greatly explored.
Dr. Vásquez has a strong interest in expanding scientific knowledge of race and ethnic differences in physical activity and sedentary behavior among people living with HIV. Her three interconnected research themes are: (1) Examining physical activity prevalence and its relationship with adverse and positive health outcomes in older adults living with HIV. (2) Examining the individual-level indicators and the ecological impact of social context which contributes to differential health outcomes in older adults living with HIV, in particular Latinos. (3) Exploring new ways to assess psychosocial and health behaviors among older adults of diverse ethnic background in epidemiological studies. In addition, she is a mentee with the Program to Increase Diversity among Individuals Engaged in Health-Related Research (PRIDE). Vásquez is also an affiliated investigator with the Study of Latinos (SOL) and part of the Physical Activity Writing Group and the Aging Writing Group for this project. She is an alumna of the National Institute of Aging Butler-Williams Scholars Program.
