Hayes, Patrick

HAYES, Patrick

Professeur agrégé

Atmospheric particles influence the climate and harm public health. The research in Professor Hayes’ group seeks to better understand the chemistry of these aerosols, which is necessary to determine their environmental impact. In addition, the group is also interested in the chemistry of mineral surfaces.

Masson, Jean-François

MASSON, Jean-François

Professeur titulaire, Directeur de département

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.

Sauvé, Sébastien

SAUVÉ, Sébastien

Professeur titulaire

Professor Sauvé works on the mobility and bioavailability of “traditional” contaminants like lead and cadmium, and on compounds of emerging interest, like drugs, cyanotoxins and nanoparticles. His work focuses on analyzing contaminants, their chemical speciation, environmental fate and potential impacts.

Thibault, Pierre

THIBAULT, Pierre

Professeur accrédité, Professeur titulaire

Our research program focuses on the development and application of proteomics and bioanalytical mass spectrometry to the identification of trace-level proteins in complex cell extracts. Our research efforts bring a multidisciplinary team approach using methods and techniques from bioanalytical chemistry, protein chemistry, biochemistry and cellbiology.

More specifically, our research interests span from the development of cell fractionation methods and protein enrichment techniques for phospho- and glycoproteins to the coupling of multidimensional capillary liquid chromatography to mass spectrometry and its application to the identification of post-translational modifications (sites and stoechiometry). We are also developing chemometric and bioinformatics tools for data mining of peptides in complex protein digests. These different tools are used in proteomics research programs to gain further insights to complex cell biology paradigms such as organelle biogenesis (phagosome and endosome), cell signalling in cancer, and the identification of peptides presented by the major histocompatibility complexproteins.

Waldron, Karen

WALDRON, Karen

Professeure titulaire

Professor Waldron’s group uses capillary electrophoresis with laser-based detection and mass spectrometry to identify proteins and peptides of biological importance. The group develops enzyme microreactors and methods for micro-scale sample preparation and separation for applications in environmental and biomolecule analyses.

Wilkinson, Kevin James

WILKINSON, Kevin James

Professeur titulaire

Professor Wilkinson and his group seek to understand the biophysicochemistry of biological and environmental systems. Their work is primarily aimed at improving our understanding of the bioavailability and mobility of environmental contaminants, in part by developing sensitive analytical techniques for heterogeneous systems.
