Research Summary

Our group uses synthetic organic chemistry to build molecules designed to perform specific chemical and biological tasks. Current projects fall in three categories: optimizing compounds for enhanced pharmacodynamic and pharmacokinetic attributes, probe compound development for elucidating function and regulation, and syntheses of structurally complex natural products that produce desirable phenotypes.  All of these molecule building efforts have the conjoined goal of advancing new ideas in synthetic organic chemistry. In addition, through synthesis the creation of new chemical matter arises providing a competitive edge in our projects’ translational potential
