Charlie joined Sigma Research in December of 2014 following the completion of an MSc in Public Health (Health Services Management) at the London School of Hygiene and Tropical Medicine. His primary role is to undertake the formative research and process evaluation on the PANTHEON trial of HIV self-testing among gay men and other MSM, but he also works on his own pilot study of motivations and barriers to PrEP use for black men who have sex with men (MSM) in London.
Charlie has worked in various capacities in sexual health in the UK and in West Africa developing and delivering health promotion, harm reduction and peer support services. His previous research has focused on gay male pornography, online representations of sexual risk and HIV testing policy.
