John Williams Lab
Research Lab Overview
Our research primarily focuses on structural and biophysical methods to identify sources of energy additivity and multivalency in macromolecular complexes and use these properties to develop new tools and novel therapeutics. Based on an ‘atoms-up’ approach, my research team and I have developed chemically-induced molecular traps (Varma, 2010); tumor-activated, masked antibodies (Donaldson, 2009); and monoclonal antibody (mAb) technology called meditopes (Donaldson, 2013, Bzymek 2018, King 2018). One of our most successful efforts to date, the generation of a tumor-activated, anti-CTLA4 mAb, is now in a phase 1/2 clinical trial at Xilio Therapeutics, a company co-founded by Dr. Williams.
