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.

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 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.

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.

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.

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.
