I am a Sir Henry Dale Senior Senior Research Fellow at the Institute for Global Health (IGH) at University College London. My research focuses on the social determinants of infectious diseases, mainly on HIV and mainly in sub-Saharan-Africa. I work increasingly on the impact of social networks on behaviour and health outcomes. I have a side interest in methods to either improve data collection or account for imperfect data collection during analysis.
I am also affilliated with Africa Health Research Institute (previously K-RITH and Africa Centre for Population Health) in KwaZulu-Natal, South Africa. As part of my ongoing work with the HAALSI cohort I am now affiliated with the MRC/Wits Agincourt Rural Public Health and Health Transitions Research Unit. I remain affiliated with the Harvard Chan School, specifically with the Department of Epidemiology and the Harvard Center for Population and Development Studies.
