    I am a board certified internal medicine and infectious diseases physician who has been caring for persons living with HIV since 2004. I care for a variety of persons living with HIV but have a special interest in persons newly diagnosed, in the successful aging of persons living with HIV, and in HIV prevention (pre-exposure prophylaxis or PrEP).

    I am an Associate Professor of Medicine in the Division of Infectious Diseases and Global Public Health and participate in clinical and translational HIV research at the AntViral Research Center and through the Center For AIDS Research (CFAR). As a member of the leadership team of the CFAR Clinical Investigation Core I assist investigators in the performance of clinical and translational HIV research by assisting with study design, study implementation, participant recruitment, research regulatory processes, and data safety monitoring. Our Core also allows the generation of preliminary data and the performance of patient oriented research through our linked patient database and specimen repository.

    Currently, my research interests stem from the “bedside-to-bench”, in that I pursue research questions that directly respond to the day-to-day needs of my patients. Examples of my current research interests include a better understanding the barriers and facilitators that contribute to poor HIV linkage and retention, a better understanding of the biology and delivery of PrEP for HIV prevention and the impact of inflammation and other factors on the successful aging of persons living with HIV.

    I also participate in the mentoring and education of medicine residents and infectious diseases fellows historically participating in UCSD’s medical microbiology and HIV pharmacology courses along with weekly educational conferences in the departments of medicine and infectious diseases along with community-based and international lecturing on various HIV topics.
