I am a researcher at the University of the Witwatersrand, School of Clinical Medicine, Department of Family Medicine.
I hold a Doctor of Medicine (MD) degree (equivalent to MBBCh) from the University of Dar es Salaam, Tanzania, and an MSc in Epidemiology from Harvard University, USA, and a Ph.D. in Epidemiology from the University of London (London School of Hygiene and Tropical Medicine), UK.
I am involved in teaching (supervision of undergraduate, Master, and Ph.D. candidates) and conceptualizing, designing, implementing, and analyzing rigorous quantitative observational and experimental studies (cluster-randomized trials, randomized clinical trials), systematic reviews and meta-analysis, implementation science and classical epidemiology studies. My substantive research interests have been on HIV, Alcohol and Other Drug Use, Mental Health, and Health Systems (digital health) in Africa, and a more recent interest on Global Burden of Diseases.
I am a member of editorial boards of two BMC series journals (BMC- Public Health & BMC – Global Health Research and Policy) and the PLOS One journal. I serve as an honorary lecturer at the Department of Epidemiology and Biostatistics, Muhimbili University of Health and Allied Sciences (MUHAS), Dar es Salaam, Tanzania.
