Research Description:

Overview

My laboratory has a long-standing research interest in problems at the interface of biology and chemistry. We provide access to novel compounds that are not available through commercial sources. Recent efforts include small-molecule inhibitors for enzymatic reactions, fluorescent derivatives of natural products and semisynthetic natural products, and unnatural peptides that would have better stability than wild-type counterparts.

Recent highlights involve work in the areas of cancer, infectious diseases and neuroscience, as summarized in our recent publications.
