Meet the Team
Dr. April Thames
BWITS Investigator
Dr. Thames is Professor of Psychiatry and Chief Psychologist of the Adult Division of Psychology in the Department of Psychiatry and Biobehavioral Sciences at the University of California Los Angeles. Her clinical and research expertise as a neuropsychologist focuses on the neurological, neurocognitive and functional consequences of infectious diseases and sociocultural factors, particularly in underrepresented populations. She is Principal Investigator on several grant supported studies targeting (1) The impact of lifetime stress and adversity on neurocognitive and functional outcomes in HIV (2) the impact of stereotype threat and perceived discrimination in neurocognitive performance in African Americans; (3) neurological and functional consequences of HIV in geriatric HIV adults; and (4) genetic predictors of cognitive impairment.
Dr. Marc Norman
BWITS Investigator
Dr. Norman’s primary research interest is in neuropsychological functioning in healthy normal adults and adults with neurological or psychiatric disorders. He is involved with ongoing studies in assessing cognitive and memory performance in healthy adults, especially Senior African Americans. Also, Dr. Norman is involved in research addressing the cognitive and affective implications of disease modifying therapies in Multiple Sclerosis as well as research in Epilepsy. Additionally, Dr. Norman has served as an ad hoc reviewer for Neuropsychiatry, Neuropsychology, and Behavioral Neurology.
Dr. Sarah Banks
BWITS Investigator
Dr. Sarah Banks is the Director of the Neuropsychology Program, Center for Memory Disorders and Brain Health. Her research uses multimodal imaging, cognitive testing and genetics to better understand sex differences in Alzheimer’s disease.
Dr. Erin Sundermann
BWITS Investigator
Dr. Erin Sundermann is a cognitive neuroscientist with a broad research scope in Alzheimer's disease and cognitive aging. Within that scope, she focuses on sex differences and the discovery of sex-specific biomarkers and risk factors for AD as well as the manifestation of Alzheimer's disease in the context of HIV.
Joy Stradford, M.S
Graduate Student Researcher
Joy Stradford graduated with a B.S. in Psychology from Howard University and a M.S. in Neuroimaging and Informatics from the University of Southern California. Joy is now a doctoral student in the SDSU/ UC San Diego Joint Doctoral Program in Clinical Psychology under the mentorship of Dr. Erin Sundermann and Dr. Sarah Banks. Joy is interested in identifying race and sex disparities in Alzheimer’s Disease and Related Dementias (ADRD), and uncovering solutions to promote better health outcomes for minoritized communities. Joy also has a specific interest in the interaction between grief and health outcomes in older adults.
Linisa Williams, B.S.
Clinical Research Coordinator
Linisa Williams, a graduate of the University of California, San Diego, holds a Bachelor of Science in Clinical Psychology. Her academic pursuits are focused on the intersection of community-based research and health disparities. With a goal of contributing to a deeper understanding of the factors affecting health outcomes in underserved communities, Linisa plans to further her education in Clinical Neuropsychology.
Michelle Jackson, PhD, MSN, ANP-BC, PMHNP-BC
Community Engagement Coordinator
Dr. Michelle Jackson is a dual board-certified Adult and Psychiatric Mental Health Nurse Practitioner with over 14 years of clinical experience. Dr. Jackson received her Bachelor of Arts in Sociology from UC San Diego and her Master of Science in Nursing and Post-Master’s Certificate from Yale University and UC San Francisco, respectively. In 2022, Dr. Jackson graduated from the University of San Diego with a PhD in nursing. Her research interests include mental health of older adults, mild cognitive impairment (MCI), Alzheimer's Disease Related Dementias (ADRD), health equity, and cultural competency in healthcare.
Breanna Holloway, PhD
Postdoctoral Research Fellow
Dr. Breanna Holloway is a postdoctoral fellow working with the BWITS research group at UCSD. She received her PhD in Clinical Psychology/Behavioral Medicine from the University of Maryland, Baltimore County. Dr. Holloway completed the APA-Accredited VASDHS/UCSD Psychology Internship Program and a 2-year T32 postdoctoral fellowship in Biopsychiatry and Neuroscience at UCSD. She was most recently awarded an NIA Diversity Supplement to expand BWITS' research aims, focusing on additional dimensions of social determinants of health and evaluating sleep disruption, particularly sleep apnea, as an additional modifiable risk factor for AD.
Nadine Heyworth, PhD
Program Manager
Dr. Nadine Heyworth is the Program Manager for the WITS/BWITS research groups at UCSD. She received her Ph.D. in Anatomy and Neurobiology at Boston University and completed post-doctoral fellowships at the Center for Translational Cognitive Neuroscience at the Boston VA Hospital, and in the Department of Psychiatry at UCSD. Her research interests focus on age-related cognitive function and the underlying neuronal processes involved in learning and memory in older adults and patients with Alzheimer's disease. She previously managed drug-intervention clinical trials at the UCSD Alzheimer’s Disease Research Center and served as the liaison between the community, researchers, and sponsors interested in clinical research studies.
