Research interests
Biochemical and biophysical studies of protein-protein/ligand interactions


Research Summary

My research has primarily focused on the use of nuclear magnetic resonance spectroscopy (NMR), and other biophysical techniques, to study the Fe(II)- and 2-oxoglutarate (2OG)-dependent dioxygenases and the penicillin-binding proteins (PBPs) and β-lactamases. These enzymes are involved in clinically important biological processes, i.e. the hypoxic response and antimicrobial resistance, respectively. Both systems are interesting from an NMR perspective because of their dynamic loops involved in catalysis and relevant interactions with ligands. My work includes enzyme mechanistic studies, protein-protein/ligand interactions, protein conformational changes, and method development for inhibitor discovery.
