I am a Senior Research Associate in the Institute for Global Health at University College London. In this role I am involved in a range of research projects relating to HIV prevention including several at the Africa Health Research Institute in KwaZulu-Natal, South Africa.
I hold Visiting Scientist positions at the Harvard T.H. Chan School of Public Health in the Department of Epidemiology and at the Harvard Center for Population and Development Studies, relating to my work with Dr. Donna Spiegelman on risk factors for HIV in high-risk populations in Tanzania, and with Dr. Lisa Berkman on the social support networks of older South Africans.
My research focuses on the social, and particularly socioeconomic, determinants of infectious diseases (to date, sexually transmitted infections and tuberculosis). I prioritize analyses of interconnectedness in order to discover how the characteristics and behaviours of others place us at risk for ill-health. While much of my work focuses on sub-Saharan Africa, in particular South Africa, I have also worked on data from Brazil, the United Kingdom and the United States.
I was previously a postdoctoral research fellow at the Harvard Chan School in the Department of Global Health and Population, where I worked with Dr. Till Bärnighausen on risk factors for HIV infection in South Africa, Uganda and Zambia. As part of this postdoctoral position I also worked with Dr. Jukka-Pekka Onnela from the Department of Biostatistics on methods for the analysis of network data, and Dr. Victor De Gruttola on innovative study designs for cluster randomized trials. I previously completed a doctoral degree in the Department of Social and Behavioral Sciences.
