Uwe Kortshagen is the James J. Ryan Professor and a Distinguished McKnight University Professor and Head of the Department of Mechanical Engineering at the University of Minnesota. He is also a member of the graduate faculties of Physics and Chemical Engineering and Materials Science. His work is in the areas of nonthermal plasmas at low and atmospheric pressures, kinetic theory of plasmas, and in the use of plasmas in materials science and renewable energy technology. His work has been published in more than 180 articles in peer-reviewed journals and more than 300 invited and contributed conference presentations.

Kortshagen earned his Diploma degree in Physics in 1988, and his Ph.D. in Physics in 1991 from the Ruhr-University Bochum, Germany, under Professor Hans Schlüter. He came to the U.S. in 1995 with a Lynen Fellowship of the Alexander von Humboldt Foundation and spent a year at the University of Wisconsin-Madison. He earned the Habilitation in Experimental Physics at the University of Bochum in 1995. In 1996, he joined the Department of Mechanical Engineering at the University of Minnesota as Assistant Professor, where he was promoted to Associate Professor in 1999, and to Full Professor in 2003. He served as President of the International Plasma Chemistry Society and is a Fellow of the American Society of Mechanical Engineers, the Institute of Physics (London, UK), and the International Plasma Chemistry Society. He was awarded the 2015 Plasma Prize of the American Vacuum Society.
