Jan J. Dubowski obtained an MSc in solid state physics (1972) from the University of Wroclaw (Poland) and a PhD in semiconductor physics (1978) completed at the Polish Academy of Sciences in Warsaw (Poland). After spending 21 years of his research career at the National Research Council of Canada (Ottawa), he joined the Faculty of Engineering of the Université de Sherbrooke (Québec, Canada) where he holds the position of a Full Professor. Since 2003, he has been carrying out innovative research focused on exploring the optical properties of epitaxial nanoheterostructures of III–V semiconductors for sensing of surface-immobilized electrically charged biomolecules. He has published over 200 research papers, reviews, book chapters and conference proceedings, and he is a holder of six international patents. He is a Fellow of SPIE—the International Society for Optics and Photonics, and a member of the Canadian Association of Physicists and the American Physical Society.
