Research Focus

My laboratory has focused on low molecular weight aromatic hydrocarbons that produce lung injury. These chemicals undergo metabolic activation to generate reactive metabolites which become bound covalently to proteins. Work in the lab is attempting to understand what proteins are critical to the cytotoxicity that ensues from exposure to these reactive metabolites, which amino acid residues are adducted and how these alter the structure/function of the adducted proteins. These data will be used to develop biomarkers of adducted urinary peptides that are tightly tied to the mechanisms of toxicity and that could be applied to exposed human populations.
