Home Mentor: Michael Yin, MD
Dr. Odlum is an Assistant Professor at Columbia University in the School of Nursing. She holds a Bachelor's in Nursing from Syracuse University and graduate degrees in Public Health and Education from Columbia University. Dr. Odlum is a named HIV Prevention Trials Network (HPTN) Domestic Scholar and the Robert Wood Johnson Foundation (RWJF) New Connections Scholars.
Dr. Odlum's program of research centers on the development of technology-enhanced interventions for improved health outcomes in populations aging with HIV. Accordingly, she intends to explore the complex needs of older adults living with HIV to understand and address the biological, behavioral, psychological and social factors that impact health and quality of life outcomes. She is interested in designing interventions to support symptom self-management. Her current research, includes an NIH funded fatigue self-management pilot intervention, successfully implemented, in a population of Latinos 50 and over aging with HIV. Dr. Odlum's work also includes the development of narrower HIV and aging-related comorbidity phenotypes with greater clinical validity for intervention efficacy. Her published research includes the analysis of clinical data and has identified key differences in comorbidity-related outcomes for HIV infected and uninfected populations.

Asante Kamkwalala, PhD
UCSD Mentors: Ron Ellis, MD & Erin Sundermann, PhD
Home Mentor: Leah Rubin, PhD
Dr. Kamkwalala is a researcher focusing on clinical cognitive neuroscience, and currently holds a position as a post-doctoral research fellow in the Department of Neurology, Division of Neurovirology and Neuroimmunological Infections at the Johns Hopkins University School of Medicine. She obtained her PhD in Cognitive and Systems Neuroscience in 2019 from the Vanderbilt Brain Institute, in Nashville, TN, and holds a Bachelor's degree in Neuroscience and Behavioral Biology from Emory University in Atlanta, GA. She also recently was awarded a Young Investigator Scholarship to participate in the Conference on Retroviruses and Opportunistic Infections (CROI) 2020.
Her research interest focuses on the neurobehavioral consequences of aging with chronic HIV infection, particularly the effects of traumatic experiences and stress. Her post-baccalaureate research work centered on behavioral outcomes of civilian PTSD symptoms in low-income, chronically stressed predominantly African-American urban populations. Her doctoral research focused on cognitive aging, and the dysfunctional neurotransmitter systems that may contribute to the accelerated pattern of cognitive aging in HIV-infected adults, supported by funding through the Vanderbilt Clinical and Translational Science award, as well as a pilot grant from the Vanderbilt Center for AIDS Research (CFAR). Under the guidance of Dr. Leah H. Rubin, MPH, PHD, her current research focus bridges these two previous projects, investigating altered neurophysiological and cognitive correlates of stress exposure and PTSD in PLWH.
Avery Matthews, MD
UCSD Mentors: Steve Huege, MD, Sara Gianella, MD, and Maile Karris, MD
Dr. Matthews is currently a geriatric psychiatry fellow at the University of California, San Diego, where she has provided both inpatient and outpatient care to older adults. She received a master's degree in basic biomedical science and her medical degree from New York University. Prior to medical school, virology was her focus. She conducted research on coronavirus spike protein at the University of Pennsylvania. She studied herpesvirus at Columbia University, looking at HSV1 ICP27 modeling trigeminal root ganglion infection in mice and performing initial studies on the drug doxovir as a possible treatment. She examined toxin-encoding S. aureus bacteriophages at New York University. As a medical student, she rotated at the Daniel C. Leicht Center for outpatient HIV care at Gouverneur Hospital and in Bellevue Hospital's inpatient HIV service, and she attended an American Psychiatric Association workshop on HIV psychiatry. She plans to meld her clinical interests-- persons living with HIV and older adults with neurodegenerative diseases-- with her research interests in virology. Her proposed research hopes to determine whether herpesvirus central nervous systems infections contribute to HIV-associated neurocognitive disorder.

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 is an Assistant Adjunct Professor at UCSD. Currently, her research program has two major themes: (1) characterizing sex differences in the trajectory diagnosis, risk factors and biomakers of Alzheimer's disease and (2) investigating the manifestation of Alzheimer's disease in the context of HIV. Along with her colleagues at the HIV Neurobehavioral Research Center, she is part of a project that aims to develop empirical, neuropsychological methods to discriminate HIV-infected individuals that are on the AD trajectory from those with HIV-associated neurocognitive impairment.
Samir Sabbag, MD
UCSD Mentor: Mariana Cherner, PhD
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.
