My group is interested in elucidating enzyme-catalyzed transformations and their application involved in natural products biosynthesis. Special approaches include organic synthesis, biochemical assays and molecular biology. Our long term goal is to apply chemo-enzymatic approach in producing important molecules for therapeutic potential, and in expanding the repertoire of enzyme catalysis.
