She is also working with Dr. Matthew Freeman to design a project investigating the impact of an enhanced, demand-side sanitation and hygiene promotion model on trachoma and sustained behavior change in Ethiopia. Maryann has over eight years of experience in international public health, and is experienced in designing and managing international programs and research projects, providing technical guidance to ensure appropriate implementation of various infectious disease programs and research studies, developing and managing monitoring and evaluation frameworks, and conducting epidemiological investigations to identify and interrupt environmental drivers of infectious disease transmission. She has developed, evaluated, and implemented disease surveillance and preparedness activities for various infectious diseases, including emerging, reemerging, and neglected tropical diseases in 11 countries in Asia, Africa, and Central America. Maryann received her Master of Public Health in Global Environmental Health from the Rollins School of Public Health in 2007, and a Bachelor of Arts in Psychology with minors in Medical Anthropology and Chemistry from Southern Methodist University in 2004.

Marieke Heijnen is a PhD candidate and research assistant in the Environmental Health group at LSHTM, focusing her research on shared sanitation facilities. Specifically, she has conducted a systematic review comparing shared sanitation facilities with individual household latrines, and analysed DHS and MICS surveys to assess the scope of shared sanitation globally and regionally. As part of her fieldwork she has conducted a cross-sectional survey in slums in Orissa, focusing on the users of shared and private sanitation. Prior to starting her PhD, Marieke worked at UNICEF Malawi and MSF-Holland. She has an MSc in Infectious Disease Control from the London School of Hygiene and Tropical Medicine and an MSc in Epidemiology from Maastricht University.

Abu Mohd Naser Titu, Ph.D, MPH  is a post-doctoral fellow whose research interests include evaluation of WASH interventions in low-income countries as well as chemical contamination of water. Naser has four years of experience working with the International Centre for Diarrhoeal Disease Research, Bangladesh (icddr,b) before starting his Ph.D. He has worked with the WASH Benefits trial and has implemented another RCT evaluating the individual and combined impact of point-of-use chlorination and safe storage on childhood diarrhea. He has explored the interaction of groundwater iron contamination and point-of-use chlorination. As part of his Ph.D. dissertation, Naser explored the health impact of managed aquifer recharge (MAR) on blood pressure and kidney markers of the population residing in southwest coastal Bangladesh. In his post-doctoral research, he is exploring the associations between drinking water minerals and cardio-metabolic health of the population.
