Research

From bacteria to humans, the life-cycle of a species depends on an delicately-balanced network of protein-protein interactions in space and time. We investigate a small subset of these interactions using a host of biophysical and biochemical techniques including solution-state nuclear magnetic resonance (NMR) methodology and recently, X-Ray crystallography.

Our current research topics include:
Intracellular signalling involving the Src-family kinases.
Structure and organization of the RNA polymerase complex in cystoviruses.
Development of novel NMR methods to study correlated dynamics on multiple timescales in proteins.
Development of NMR methods to obtain structural constraints in large proteins/complexes.
