Biography

Dr. Holzman received his Ph.D. from the Department of Electrical and Computer Engineering at the University of Alberta in 2003. In 2004-2005, he carried out research in ultrafast all-optical switching as an NSERC Postdoctoral Fellow in the High-Speed Electronics and Photonics Group at the Swiss Federal Institute of Technology (ETH) in Zürich, Switzerland. He is now a Professor in the School of Engineering at the University of British Columbia’s Okanagan campus and group leader of the Integrated Optics Laboratory.
