Research: My broad research goal is to understand the molecular mechanisms of inflammatory disease process in order to inhibit progression of the disease. My current studies investigate (1) how arsenic increases atherosclerosis and which mechanisms mediate its cardiotoxicity and, (2) the mechanisms by which lipid derived aldehydes affect atherogenesis and how the effects of these aldehydes could be prevented or therapeutically minimized to decrease atherosclerosis.
