Her research focuses on using implementation science to guide the translation of STD and HIV prevention research into clinical and public health practice. She is currently a protocol Co-Chair and site Co-Principal Investigator of The Demo Project, an NIH-funded research study assessing the delivery of pre-exposure prophylaxis (PrEP) in STD and community health clinics. She is also the site co-PI of the STOP Study, which is evaluating the use of 4th generation HIV Ag/Ab tests and RNA pooling for the detection of acute HIV in high prevalence settings.
