Research Interests: Study of: (a) the relations of cardiovascular risk factors and diseases to neurocognitive function, and examination of underlying brain mechanisms using neuroimaging. (b) biopsychosocial factors in cardiovascular risk and disease; (c) race- and socioeconomic- status related health disparities in brain, neurocognitive, and cardiovascular outcomes; and (d) individual differences in the magnitude and patterning of acute cardiovascular responses to mental stress.
