Climate change, degrading water resources, and economic and population growth are increasing the need for new science and technologies at the Water-Energy-Food Nexus. In enabling new and improved technologies to tackle these issues, a thermofluids systems approach is essential to guide the design of new nanomaterials, allowing for performance improvements and new capabilities. Following this approach, thermodynamic design of water treatment membrane technologices such as membrane distillation (MD) leads to innovations with superhydrophobic nanostructured surfaces for heat transfer. New structures can also be created and optimized with this approach to operate in large systems. Nanomaterial self-assembly techniques can be guided by thermofluids designs to make macro-scale membrane systems with photonic properties for catalysis and solar distillation.
Dr. David Warsinger completed his B.S. and M.Eng at Cornell, and his PhD in Mechanical Engineering at MIT: he completed his graduate studies in a combined 3 years. David’s research focuses on the water-energy nexus, with approaches from thermofluids and nanoengineering. Currently, David is a Postdoc at MIT and beginning a joint Postdoc at Harvard. Prior to starting his PhD, David worked at the engineering consulting firm Arup, where he performed energy and sustainability analysis and designed heating and cooling systems. David is a coauthor of 22 published and 6 submitted journal and conference papers, and a co-inventor of 13 filed or awarded patents. He is also involved with entrepreneurial endeavors, including demonstrating batch reverse osmosis with MIT startup Sandymount, and cofounding Coolify, a startup providing refrigeration via phase-change thermal storage for farmers in developing economies. Notable awards David has earned include the national dissertation award from UCOWR, the highest GPA award for his Masters, 9 presenter awards, and the MIT institute award for best research mentor for undergraduate students.
