Professor Masson develops spectroscopic biosensors for the analysis of biomolecules present in medical samples. He studies the properties of nano- and microstructures to improve the sensitivity of instruments and the properties of surface chemistry to improve analysis selectivity in biological fluids.

Professor Vallée-Bélisle and his group are inspired by nature in developing biotechnologies and nanotechnologies (biosensors, nanomachines, etc.) aimed at making real improvements in global health and environmental issues.
