Joshua Mendelsohn MSc PhD

Distance Learning Tutor & Assistant Professor


I am an Assistant Professor in the College of Health Professions at Pace University in New York and a Distance Learning Tutor at LSHTM. I am a social epidemiologist working primarily on studies of HIV treatment and prevention. I completed a Postdoctoral Fellowship at the CIHR Social Research Centre in HIV Prevention, Dalla Lana School of Public Health, University of Toronto. I received my PhD from the Department of Infectious Disease Epidemiology, LSHTM, where I was supervised by Professor David Ross. We collaborated with the United Nations High Commissioner for Refugees (UNHCR) on a study that examined HIV treatment outcomes among refugees and local host communities in Kenya and Malaysia. I am a member of the Public Health in Humanitarian Crises Group and an Associate Managing Editor for the journal Conflict & Health. Earlier in my career, I worked as a researcher for the Demos' Science Policy Team and as a consultant for Goss Gilroy on a variety of environmental and health sector projects. I hold a PhD in Infectious Disease Epidemiology (LSHTM), an MSc in Environmental Change and Management (University of Oxford) and a BSc (Honours) in Zoology & Psychology (University of Toronto).




At LSHTM, I am the Module Organizer for Conflict and Health offered within the Public Health Distance Learning program. I also serve as a Tutor on the Epidemiology of Communicable Diseases module. Previously, I taught on in-house courses in Statistics for Epidemiology and Population Health and Basic Epidemiology at LSHTM, and Introduction to Qualitative and Quantitative Research Methods at the School of Public Policy, University College London.


My research interests include HIV and AIDS, antiretroviral therapy, infectious disease control, and mobile populations, with a focus on humanitarian settings. I am currently involved in studies on the feasibility of early ART ("treatment as prevention") for reducing incident HIV infections (China), and the impact of antiretroviral therapy on relationship quality among HIV-serodiscordant relationships (Canada). I continue to be engaged work on HIV treatment outcomes among refugees in Kenya. I have received generous support from the Canadian Institutes for Health Research, UNHCR, the University of London Central Research Fund, and the Parkes Foundation.
