Experiences & Accomplishments
I trained in Medicine in the UK and undertook further training in internal medicine, infectious diseases, and STI/HIV. I undertook additional scientific training in Medical Anthropology (MSc), Biological Sciences (PhD), and Global Health (MPH). Prior to moving to Johns Hopkins I have worked in the UK, South Africa, the Gambia, and Uganda. I am an Associate Professor in the Infectious Diseases Division at Johns Hopkins Bayview where I am building a research portfolio around sexually transmitted infections (STI)/HIV in the US and sub Saharan Africa. Since January 2020, I have been Chief of STI for Baltimore City Health Department (BCHD). I see patients with or at risk of HIV at the John G. Bartlett Specialty Practice at Hopkins Hospital, and more recently I have established a dedicated clinical service providing care to patients with, or at risk of, HIV/STI and for HIV PrEP at Johns Hopkins Bayview.
I am particularly interested in interactions and synergies between HIV-STI and prevention strategies; near-patient HIV/STI diagnostics, genital ulcer disease and extra-genital STIs. My focus is on utilizing near-patient, rapid tests to improve linkage to care and treatment outcomes for HIV, STI and HIV PrEP. Additionally, I am actively researching how improved access to STI/HIV diagnostics using at-home self-collected samples can improve linkage to care.
I am also involved in research related to antenatal syphilis as well as gonorrhea surveillance in Kampala, Uganda as well as developing diagnostic capacity for other STI.
