My interests lie in using chemical tools to probe biological mechanisms of disease, with the ultimate goal of developing a better understanding of heart disease to develop novel therapeutics. Currently, my work focuses on the processing mechanisms of PCSK9, a protein that causes elevated cholesterol levels, so as to develop new drug targets against atherosclerosis.
