Research Interests
My research aims at linking contaminant bioavailability to toxicity, especially for aquatic organisms exposed to metals and metallo-nanomaterials through solution and diet. I am especially interested in improving our understanding of the physiological and geochemical processes that influence metal bioaccumulation. Biodynamic modelling and enriched stable isotope tracers are the centerpiece of my work. For instance, I develop and refine biogeochemical methodologies to quantify responses of organisms to metal-stresses. Specifically, I conduct experiments where I employ biodynamic principles and isotope tracers to investigate the relationships between contaminant exposure and bioaccumulation, as well as between contaminant fluxes and toxicity. The parameterization of species-specific and metal-specific processes (e.g., feeding rates, assimilation efficiencies, loss and detoxification rates) allows predicting the risks and effects of metals and metallo-nanomaterials exposure.
