I received my PhD in Physics from the University of Waterloo in 2000, and my MSc in Optics from Chinese Academy of Science in 1990.
Prior to joining Laurier, I was an Optical Engineer at Lightwave Solutions at San Diego (2001-2003) and a Research Scientist at JDS Uniphase, Ottawa (1999-2001).
My research interests lie in the field of computational/experimental photonics and plasmonics.
