The people in the lab

A small group by design. Students here build and align their own instruments, and most leave with their name on a paper.

Principal investigator

Dr Kevin C. Hewitt

Professor in the Department of Physics and Atmospheric Science at Dalhousie University, with over twenty-five years applying Raman spectroscopy across condensed matter physics, materials science and biomedical optics.

He has attracted $2.5M in research grants as principal investigator and $7.3M in joint research grants, and a further $2.2M in science education and outreach grants. He has held visiting professorships at Stanford University and the BC Cancer Agency, and serves as an external grant reviewer for CFI, NSERC and CIHR, and as a referee for the Journal of Biomedical Optics and Optics Express.

He sits on committees concerned with diversity in physics and is a member of the Nova Scotia Institute of Science and the Canadian Association of Physicists.

His public engagement — Imhotep’s Legacy Academy, the Canadian Black Scientists Network, and the participation of Black students in science — has been covered continuously since 1999.
