Shoichet Laboratory


The Shoichet lab seeks to bring chemical reagents to biology, combining computation and experiment. In a protein-centric approach, molecular docking, we discover new ligands that complement protein structures. Using a ligand-centric approach, we discover new targets for known drugs and reagents. A focus for both is the discovery of reagents to modulate G-Protein Coupled Receptors (GPCRs).
