I received my PhD in Physics in 2003. My recent research activities focus on nanostructured group-IV semiconductors embedded in fused silica glass for applications in photonics, optoelectronics and photovoltaic. I am also strongly involved in the area of ion implantation for advanced material synthesis, matter modification and analysis, as well as space environment simulations and testing under ion beam exposure. I joined F. Rosei’s group in November 2013 to work on a strategic NSERC research project related to the development of germanium fiber Bragg gratings (FBG) and Er-doped fiber amplifiers (EDFA) operable in harsh environments.
