Costas Sarris, Ph.D.
Professor of Electrical and Computer Engineering
University of Toronto

Costas Sarris received a Ph.D. in Electrical Engineering and a M.Sc. in Applied Mathematics from the University of Michigan, Ann Arbor, in 2002. He also received a Diploma in Electrical and Computer Engineering (with distinction) from the National Technical University of Athens (NTUA), Greece, in 1997. He joined the University of Toronto in 2002, where he is now a Full Professor at the Department of Electrical and Computer Engineering. In 2009-2010, he was a Visiting Associate Professor at the Department of Electrical and Computer Engineering, University of Illinois at Urbana-Champaign.

His research interests are in the area of numerical electromagnetics, with emphasis in high-order, multiscale/multi-physics computational methods. He is involved with basic research in novel numerical techniques, as well as applications of time-domain analysis to wireless channel modeling, wave-propagation in complex media and meta-materials, electromagnetic compatibility/interference (EMI/EMC) problems and modeling under uncertainty. He also teaches undergraduate courses in electromagnetics and wireless systems, and graduate courses in numerical electromagnetics and antenna theory.

Prof. Sarris was a recipient of the 2013 IEEE MTT-S Outstanding Young Engineer Award. He also received the Early Researcher Award from the Ontario Government in 2007, the Canada Foundation for Innovation New Opportunities Fund Award in 2004, and a Student Paper Award at the 2001 International Microwave Symposium. His students have received student paper awards at the 2015 IEEE Wireless Power Transfer Conference, the 2009 IEEE MTT-S International Microwave Symposium, the 2008 Applied Computational Electromagnetics Society conference and the 2008, 2009, 2018 IEEE International Symposia on Antennas and Propagation.

On the teaching side, Prof. Sarris received the Gordon R. Slemon (teaching of design) award in 2007 and a Departmental Teaching Award (by confidential vote of ECE students, for excellence in undergraduate teaching) in Fall 2018, 2016 (3rd year Fields and Waves) and Spring 2005 (4th year Radio and Microwave Wireless Systems).

Prof. Sarris is the Editor-in-Chief of the IEEE Journal of Multiphysics/Multiscale Computational Techniques (JMMCT) and the Chair of the IEEE MTT-S Technical Committee on Microwave Field Theory (MTT-15). He was an Associate Editor for the IEEE Transactions on Microwave Theory and Techniques (2009-2012) and the IEEE Microwave and Wireless Components Letters (2007-2009), as well as Guest Editor of the IEEE Microwave Magazine Special Issue on Time-Domain Methods for Microwave CAD (April 2010). He was the Technical Program Committee Chair for the 2015 IEEE Int. Symposium on Antennas and Propagation and URSI North Americal Meeting in Vancouver, BC; Vice Chair of the Technical Program Committee of the 2012 IEEE MTT-S International Microwave Symposium in Montreal, QC; Technical Program Committee co-Chair for the 2010 IEEE Int. Symposium on Antennas and Propagation and URSI North Americal Meeting in Toronto, ON. He has served as Chair of the Sub-Committee on Time and Frequency Domain Methods of the Technical Program Committee of the IEEE MTT-S International Microwave Symposium. Professor Sarris was an Associate Chair of the Division of Engineering Science, University of Toronto, between September 2011 and July 2014.
