Research Interests

  • Chemical Biology -  We are working to capitalize on our discovery of pyrrolysine, the 22nd genetically-encoded amino acid, to engineer proteins with novel structures and properties.
  • Protein crystallography - We wish to use protein crystallography to elucidate the structure function relationships of proteins.
  • Protein Delivery -  We are exploring new technologies to deliver proteins to cells.
