Ryan is interested in using synthetic membranes to improve the sustainability of water treatment, electrical energy generation, and energy storage technologies. Many technologies at the water-energy nexus require precise separations between species of similar physicochemical characteristics, which conventional polymeric membranes have limited ability to accomplish. Ryan takes inspiration from biological channels and seeks to create a synthetic membrane that is able to exclusively transport a single ionic species. Ryan is financially supported by an American Water Works Association Abel Wolman Fellowship.


Prior to Yale, Ryan received a B.S. in Civil Engineering from the University of Arkansas and was the College of Engineering’s top graduate. Ryan also was a Gates Cambridge Scholar at the University of Cambridge, where he completed an M.Phil. in Engineering for Sustainable Development and received the London Water Conservator’s Best Dissertation Prize. During his undergraduate and master’s degrees, his research focused primarily on water service provision in low- and middle-income countries. He worked on point-of-use ceramic water filters for applications in rural South Africa through an NSF Research Experience for Undergraduates. While at Cambridge, the aim of his dissertation was to determine causal factors of intermittent water services in rural Bangladesh, Pakistan, Ethiopia, and Mozambique.


Aside from engineering, Ryan enjoys the outdoors and sports. He likes running, road biking, and ultimate frisbee. He enjoys hiking in the mountains surrounding Connecticut on the weekends.
