Research Summary

Building molecules using synthetic organic chemistry is the focus of our research. The compounds targeted for synthesis fall in three categories; probe compounds for elucidating function and regulation, optimized compounds with enhanced pharmacodynamic and pharmacokinetic attributes, and structurally complex natural products.  All of these molecule constructing programs are focused on advancing new ideas in small molecule-based therapeutics. In particular, synthesis in the laboratory enables the creation of new chemical matter that provides a competitive edge enhancing the projects’ translational potential.
