Dr Peter MacPherson is a Wellcome Trust Clinical Research Fellow and Senior Lecturer at Liverpool School of Tropical Medicine, UK. He holds a PhD from LSTM, an MRes from University of Liverpool, an MPH from Harvard University, and did his undergraduate medical training at the University of Aberdeen. Peter is based at the Malawi-Liverpool-Wellcome Trust Clinical Research Programme in Blantyre, Malawi, where he leads the Public Health Research Group. His research focuses on the epidemiology of the HIV and TB co-epidemics in sub-Saharan Africa, and on the development and evaluation of interventions to improve case detection and access to treatment. During his present Wellcome Fellowship, Peter is undertaking a number of randomised controlled trials of HIV/TB interventions, including a pragmatic randomised controlled trial of optimised HIV/TB screening using novel diagnostics and linkage to care among adults attending health centres with symptoms of tuberculosis (PROSPECT Study); an intensive TB/HIV household contact tracing intervention; and a male-partner-based index contact tracing study. During his Wellcome Clinical PhD, Peter did a cluster-randomised trial of a novel HIV self-testing and home initiation of treatment intervention among 17,000 adults in urban communities in Malawi. Peter is an Honorary Consultant in Communicable Disease Control at Public Health England North West.
