Professor, Environmental and Global Health
Dr. Liang’s research interests include epidemiology, ecology, risk assessment of environmentally-mediated infectious diseases, and human health impact of environmental and climate change. Over the past 15 years, he has been studying socio-environmental determinants and control of water, sanitation, and hygiene (WASH) related neglected tropical diseases (e.g. schistosomiasis and soil-transmitted helminthiasis) through both empirical and mechanistic approaches. More recently, his work has expanded to understand human exposure to water/foodborne pathogens (e.g. Campylobacter spp.) and associated infection and disease risks in the settings of low and middle-income countries (LMICs). Dr. Liang has received funding from NIH, NSF, USAID, and the Bill & Melinda Gates Foundation (BMGF) etc. to conduct research work on these areas. He has authored and co-authored more than 100 peer-reviewed research articles in journals including the Lancet, Proceedings of the National Academy of Science of USA (PNAS), Bulletin of World Health Organization (BWHO), PLoS Medicine/NTDs, and Nature Climate Change. Dr. Liang currently serves as an adviser to the World Health Organization’s Guidelines Development Group (GDG) on control and elimination of schistosomiasis.
