Current research focus?
I am interested in the effect of social determinants, such as poverty, education, housing, and segregation, on the incidence of infectious diseases and their consequences.

Exciting ongoing project(s)?
I am currently leading two NIH-funded R01 studies assessing the role of women-centered and patient-centered HIV care in mitigating the effects of adverse psychosocial factors of HIV care outcomes. In addition, I am participating in three COVID-19-related studies. One is on the effects of COVID-19 on people living with HIV infection. Another is an intervention to increase COVID-19 testing and vaccination. The last is an educational intervention to increase COVID-19 vaccination through Town Hall meetings. I also lead the Investigator Development Core of FIU’s Research Center for Minority Institutions.
