Her research explores brain-behavior relationships in disease states using a biopsychosociocultural framework. She is particularly interested in health disparities and health-related outcomes among underrepresented and disenfranchised populations. Her current work is focused on individuals with HIV/AIDS. Ongoing projects in this area include an NIMH-funded study examining longitudinal changes in the brain among HIV+ individuals as a function of HIV antiretroviral medication. Differences in healthcare quality between non-Hispanic white and African American participants, as well as factors associated with these differences, are also being examined.
