Director, Graduate Program in Reliability Engineering
Maryland Energy Innovation Institute
Ph.D., University of Pennsylvania, 1971
Professor Aris Christou previously served as the Chair of the Department of Materials and Nuclear Engineering. He currently conducts research in compound semiconductor materials and process science, radiation effects in materials and devices, manufacturing science, and reliability. From 2000-2003, Dr. Christou was the Director of the NSF Center COEDIP, the Center of OptoElectronic Devices, Interconnects and Packaging. Prior to his appointments at the University of Maryland, he was a Professor of Electronic Materials at Rutgers University, and research scientist at the Naval Research Laboratory. He has authored two books and has been the editor of three others. Dr. Christou has more than 150 publications in archival journals and 14 patents (including two pending), and has organized international conferences in GaAs devices, materials and reliability. He is a Fellow of the IEEE, a Fullbright Fellow, a recipient of the DoD-Berman Publication Awards, and an IEEE Guest Lecturer. Professor Christou was the 2004 recipient of the INEER Achievement Award (International Network for Engineering Education and Research) for achievements in international education and research in engineering, as well as the recipient of the 2007 ASM International Burgess Memorial Award "For his seminal scientific contributions in the field of electronic materials, packaging and devices." Professor Christou is a member of APS, ASM, TMS and MRS, was the past President of the Federation of Materials Societies from 2004-2006, and is presently a member of the FMS Board of Trustees.
