Current research is centered in several areas:
Our work has expanded the microbiologic spectrum of BV-associated organisms, and we continue to study predictors of infection with these bacteria, their role in diagnosis of vaginal infections, the host immune response in BV, and potential reservoirs (including sex partners) that may help explain BVs association with specific sexual practices. We are also very interested in the effects that different types of hormonal contraception may have on the genital microbiome and on risk of and activity of critical genital infections, including genital herpes.
The major objectives of work related to HIV PrEP is to evaluate the effectiveness of oral vs. vaginally delivered antiretroviral medications in preventing HIV acquisition in young HIV-uninfected women in sub-Saharan Africa. Research related to other STDs seeks to define better point-of-care diagnostic tests for common pathogens. Collaborators in these efforts include Dr. David Fredricks, Dr. Thomas Hawn, Dr. Jared Baeten, and Dr. Connie Celum.
As the Medical Director of the Seattle STD/HIV Prevention Training Center, I am also invested in delivering and evaluating excellent educational offerings to providers in practice and to medical practitioners in training. See www.seattlestdhivptc.org for more information.
