Research
Professor Gaillard's current research focuses on the study of the chemical forms (speciation) and the biogeochemical cycles of elements in aquatic systems. The chemical speciation of elements determine their toxicity and availability to microorganisms. Conversely, microbes mediate changes in oxidation state and coordination, controlling therefore the speciation of elements in natural systems.
The primary objective of his research group is to determine the analytical speciation of metals to better understand their fate in the environment and define appropriate remediation actions. To that end, he and his group are using a multi-method approach combining electrochemical, microscopic, and molecular tools.
