Research Interests:

Coming from a background in the investigation of enzyme mechanisms, protein structure/function relationships, enzyme inhibitor design/synthesis and protein engineering we are increasingly adopting and developing tools to carry out such studies in a high-throughput manner. An area of interest is in the discovery of enzyme inhibitors or chaperones as novel pharmaceuticals through high-throughput screening. Recent successes include potential treatments for diabetes and influenza. In each case we are targeting key carbohydrate synthesizing or degrading enzymes.
