Geoffrey M. Geise is an associate professor at the University of Virginia. After earning a B.S. degree in chemical engineering from the Pennsylvania State University in 2007, he proceeded to earn M.S.E. (2010) and Ph.D. (2012) degrees in chemical engineering from the University of Texas at Austin where he developed experimental techniques for measuring individual ion sorption in polymers and established a fundamental selectivity/permeability tradeoff relationship in desalination membrane materials. At the University of Virginia, his research focuses on studying the fundamentals of chemically- and electrochemically-driven small molecule transport through polymeric materials in order to engineer membranes that will address global water shortages and need for clean energy. Current focus areas include desalination membranes, ion-specific separations, non-aqueous redox flow battery membranes, and microwave dielectric relaxation spectroscopy.
