Ph.D., Stanford University, 1990
Solid oxide fuel cells, gas separation membranes, solid-state gas sensors, electrocatalytic conversion of CH4, post-combustion reduction of NOx using advanced ion conducting materials.
Prior to joining the A. James Clark School of Engineering as the founding director of the University of Maryland Energy Research Center, Professor Wachsman spearheaded the creation of the Florida Institute on Sustainable Energy at the University of Florida in Gainesville, Fla. Before pursuing his career in academia, he rose through the ranks from post-doctorate to senior scientist at SRI International. He has more than 140 publications and eight patents on ionic and electronic transport in ceramics, their catalytic properties, and device performance.
Professor Wachsman is also a frequent invited panelist on fuel cell and hydrogen energy research, ranging from the U.S. Department of Energy "Fuel Cell Report to Congress" and "Basic Research Needs Related to High Temperature Electrochemical Devices for Hydrogen Production, Storage and Use," to the National Science Foundation "Workshop on Fundamental Research Needs in Ceramics," NATO "Mixed Ionic-Electronic Conducting (MIEC) Perovskites for Advanced Energy Systems,” and the National Academies “Global Dialogues on Emerging Science and Technologies."
Current Research Projects
Profesor Wachsman has focused his career on developing advanced, efficient, energy conversion devices and technologies. His research is on ionic transport in solids and the heterogeneous electrocatalysis at their surface. This research includes the development of solid oxide fuel cells, gas separation membranes, solid-state gas sensors, the electrocatalytic conversion of CH4, and the post-combustion reduction of NOx using advanced ion conducting materials.
Most recently, his research group has made advancements in several fields related to ceramic ion conductivity, developing intermediate and low temperature solid oxide fuel cells (SOFC's), ion transport membranes, and solid state sensors. Through this research, Professor Wachsman and his team have contributed to the fundamental understanding of electrocatalysis and fundamentals of ion transport.
