A Better ToiletFor A Cleaner World
Who We Are
We are based out of Duke University’s Center for WaSH-AID, a multidisciplinary team with a mission to leverage technology innovations to address complex global challenges impacting water, sanitation, hygiene and infectious disease in resource-limited environments. We partner with many research, industry and non-profit organizations, including RTI International, Colorado State University, NASA’s Ames Research Center and the U.S. Naval Research Laboratory to develop prototype systems for safe, sanitary and affordable waste treatment.
Our team includes experts in engineering, water and sanitation, energy, and economics:

Jeff Piascik, Ph.D.
(Product Development Lead)
is a staff research scientist in Materials and Electronic Technologies at RTI International. Prior to joining RTI, he worked for MTS Systems Corporation as a applications engineer and product manager where he managed new product development and marketing for standard and custom applications. At RTI, his work has included; development of novel materials systems for bio-applications and electronic technologies, material surface functionalization for adhesion and anti-microbial properties, and MEMS-based electronic devices.
(International Development Lead)
is RTI’s Senior Director for Global Programs. Mr. Elledge has worked in 21 countries with USAID, the Asian Development Bank (ADB), the Japan Overseas Development Corporation, the Bill & Melinda Gates Foundation, and the World Bank. Over the past 20 years, his work on water and sanitation issues has focused at the national policy level and on supporting improved social infrastructure planning and service delivery at the subnational level. Mr. Elledge has supported projects in Africa, Asia, Latin America, and Eastern Europe. He served as task leader for the global USAID Environmental Health Project to develop guidance documents on sanitation policy, and he recently led a peri-urban sanitation intervention in Indonesia supported by Taiwanese partners. He holds a B.A. degree in Third World Studies from the University of the South, and a master’s degree in International Economic and Social Development from the University of Pittsburgh.
Edgard Ngaboyamahina, Ph.D., M.B.A.
(Research Scientist, Enabling Technologies)
is a Research Scientist at Duke University’s Pratt School of Engineering’s Department of Electrical and Computer Engineering. He holds expertise in electrochemical techniques applied to synthesis and characterization. Prior to joining Duke, he worked with established French companies. With the Commercial Strategic Directorate of Eléctricité de France (EDF), he analyzed the White certificates scheme from an economic perspective. At the Atomic Energy and Alternative Energies Commission (CEA), he developed new materials for electrical vehicles’ batteries. At Duke, his work currently includes the application of novel energy-efficient techniques to both disinfect liquid waste and mitigate unpleasant odor in sanitation facilities.
(Lead Combustion Engineer)
John leads the biomass cook stoves program at the EECL and is lead engineer for the solid waste gasification unit. He joined the EECL team in 2012 after spending nine years in the aerospace industry at United Launch Alliance where he developed booster propulsion systems. John also coordinates testing activities within the lab, working with industry leaders to develop and further technologies which improve living conditions in the developing world.
(Web Developer & Communications)
is a web developer at the Duke Clinical Research Institute as well as the owner of Conduit Designs, LLC, a one-man web developement shop located in downtown Durham, NC. He’s been hand-crafting sites for well over a decade (including the very site you are looking at right now) and is responsible for administering abettertoilet.org in addition to facilitating the web-based documentation and communication of RTI International’s reinvent the toilet project.
Michael Flynn (NASA Ames) – Scientist from Space Biosciences Division with expertise developing systems that convert human waste for reuse on space missions and related applications. Michael Flynn serves as technical adviser to the team.
Paul Natishan, Ph.D.
(Naval Research Laboratory)
– Head of the Corrosion Science and Environmental Effects Section at NRL with expertise in electrochemical treatment of environmental waste. He is also the past President (2009-2010) and Fellow of the Electrochemical Society (ECS) and Fellow of the National Association of Corrosion Engineers (NACE). Dr. Natishan serves as technical adviser to the team.
