One set of projects involves studying ways to improve awareness and uptake of preexposure prophylaxis (PrEP) among young, Black men who have sex with men (MSM) in Chicago. Broadly, my projects on this study involve using social network data from Facebook as a means to study effective ways of PrEP diffusion, including modeling diffusion using a variety of algorithms, and predictive modeling of missing friendship data ("links") on these networks.

Another set of projects involve studing the impact of incarceration on the HIV epidemic among Black MSM in Chicago, Houston, and Los Angeles. Incarceration causes disruption in the social and sexual networks that people maintain, both inside and outside of correctional facilities. I am modeling the impact of this disruption, and ways to link people to appropriate treatment and PrEP regimens to reduce new infections.

I have also worked on stochastic agent-based network modeling of HIV transmission in several other populations: circular migrants, pregnant women, and serodiscordant couples in various regions of Africa, and MSM in the United States.

Recognition from the academic community includes a Best Paper Prize from the American College of Epidemiology, a research feature at UNAIDS's "HIV this Month", and an Honorable Mention in the Student Award Category from the International Network for Social Network Analysis (INSNA).

Additionally, I have received the following grants as Principal Investigator:
