Michelle’s lab develops innovative approaches to screen for chemical tools and drug leads, using biophysical approaches like fragment-based drug discovery and biological approaches including high-content imaging with primary cells and organisms. Our goal is to demonstrate ‘druggability’ of new target classes and to use our compounds to discover new targets for drug discovery. Areas of interest include protein-protein interactions, allosteric and scaffolding sites in enzymes, and orphan and neglected diseases. Michelle is co-Director of the Small Molecule Discovery Center, a collaborative research and core lab that includes a high-throughput screening facility and medicinal chemistry (smdc.ucsf.edu).
