Description of Research

My primary research interest of is in biophysical chemistry of proteins, focusing on structure and function relationship. We combine high resolution X-ray and neutron crystallography to analyze the chemistry that underpins biomolecule function from their atomic structures. We are specifically interested in understanding cytochrome P450s, one of the most versatile biologic catalysts.

We are also working on understanding the structural changes that are associated with virus assembly, attachment and infection at cell membranes. We use a suite of structural techniques, including crystallography, small angle neutron scattering (SANS), and reflectometry to model the structural rearrangement undergone by virus particles during the infection process.
