Dr. Nowak's research goals are to understand the molecular pathogenesis of virally associated cancers particularly in the context of HIV infection. She is an infectious disease epidemiologist with nearly ten years of experience in laboratory sciences. Her interest in HIV began in the mid-90's and she has maintained a focus on HIV throughout her training as an epidemiologist. She is currently interested in the local immune environment and how that contributes to the persistence of high-risk human papillomavirus (HR-HPV). Antiretroviral therapy (ART) has not been associated with a decrease in HPV-associated cancers, suggesting an inability to clear HR-HPV locally with a cell mediated immune response independent of immune restoration in the periphery. To better understand what is happening locally, she is characterizing the composition of the anal microbiota among HIV-infected and HIV-unifected Nigerian men who have sex with men (MSM) as a correlate of persistent HR-HPV. Her long term goal is to identify local immunologic pathways that may be enhanced to prevent anal cancer.
