Faculty Member Since 2018
Dr. Kimberly Williams is an assistant professor at Spelman College in the Environmental and Health Sciences Program.
A native of Atlanta, Georgia, Dr. Williams graduated from the Math and Science Magnet program at Benjamin E. Mays High School. During her summers as a high school student, she also participated in the Science and Math Summer Enrichment Program held at Spelman College. Dr. Williams received her Bachelor of Science from Johnson C. Smith University where she majored in biology and minored in chemistry. As an undergrad, she participated in biomedical research programs such as the LS-AMP (Alliances for Minority Participation) and MBRS-RISE (Minority Biomedical Research Support-Research Initiative for Scientific Enhancement).
Through these programs Dr. Williams completed her 1st research experience at the University of North Carolina-Charlotte where she studied the effects of cadmium and temperature on the mitochondrial protein aconitase in the eastern oyster Crassostrea virginica. After graduating college, Dr. Williams became a post-baccalaureate fellow at the University of North Carolina-Chapel Hill where she studied developmental changes in the localization and subunit composition of a class of receptors necessary for neural plasticity, known as N-Methyl-D-aspartic acid (NMDA) receptors. Dr. Williams received her Ph.D. in neuroscience from the University of North Carolina Chapel Hill in 2015. Her T32, F31-funded dissertation identified growth factor signaling as a novel potential therapeutic adjunctive strategy to prevent neuronal damage and loss seen in HIV- associated neurocognitive disorders (HAND). In graduate school, Dr. Williams was also a HHMI scholar which certified her as a translational researcher through the Med into Grad translational medicine program. She also received certifications in college teaching and effective mentoring.
Dr. Williams completed her postdoctoral fellowship at the University of Pennsylvania as a PENN-Postdoctoral Opportunities in Research and Teaching (PENN-PORT) postdoctoral fellow, an K12-sponsored, Institutional Research and Academic Career Development Award (IRACDA) postdoctoral training program. She continued in the NeuroAIDS field as a postdoctoral fellow, and she characterized a natural flaxseed lignin, Secoisolariciresinol Diglucoside (SDG) as a novel drug candidate for HIV associated neurocognitive disorders. Through Penn-PORT, she served as a visiting professor at Rutgers-Camden University where she taught a Principles of Biology course. She also served as a visiting professor at Lincoln University where she developed and taught a Neuroimmune Disorders of the Central Nervous System course. Dr. Williams overarching career and research goals are to lead a translational research program focused on the development of new targeted therapeutics for mental health disorders influenced by neuroinflammation while increasing diversity in biological sciences through teaching and mentorship

Current Research
Our lab is interested in understanding how immune cells interact with the Central Nervous System using cross-disciplinary approaches to understand the underlying mechanisms of neuroinflammation and reveal endogenous signaling mechanisms that lead to novel therapeutic options. Macrophages and microglial cells, in particular, are major players in the neuropathogenesis of many neurologic disorders such as Post-Traumatic Stress Disorder (PTSD) and HIV-associated neurocognitive disorders (HAND), despite their differing etiologies.
Due to the success of ART, women living with HIV are reaching menopausal ages, where estrogen concentrations are significantly decreased. 30% of women living with HIV also suffer from PTSD. An understanding of effects of PTSD on HIV-induced neuroinflammation in post-menopausal women at the cellular level is needed to develop target therapeutic avenues. Estrogen, itself, has neuroprotective properties and low estrogen levels are associated with worse HIV prognosis and PTSD symptoms in traumatized women, highlighting its role as a possible therapeutic option. Our lab is interested in elucidating the role of estrogen signaling during HIV and PTSD neuroinflammation, as a potential therapeutic.
