About me

I have been a postdoctoral researcher at Northwestern University since 2009. I initially conducted research in HPV infections that cause cervical cancer. In 2013 I joined Dr. Thomas Hope’s laboratory to expand my expertise in infectious diseases and to engage in HIV translational research. It has been a great fulfillment to bridge basic research with (pre)clinical investigations aiming to improve global health through disease prevention.

Reserach Goals

Preventing sexual HIV transmission by drug delivery systems in the female reproductive tract

Projects, Experiments & Collaborations

My research focuses on acquisition of SHIV viruses in the female reproductive tract of primates treated with a new antiviral drug delivery system. In collaboration with Dr. Patrick F. Kiser’s research group we are examining TDF IVR devices in vivo, and are trying to determine efficacy of drug delivery technology to prevent viral transmission. I am also contributing to a hormonal study in macaque models where we are trying to understand how the menstrual cycle and the presence of hormonal contraceptives in female primates affect SHIV transmission.
