Proteomics and biological mass spectrometry
We primarily study the molecular basis of GPCR-mediated signal transduction, principally via the techniques of X-ray crystallography and single particle electron microscopy. By determining atomic structures of signaling proteins alone and in complex with their various targets, we can provide important insights into the molecular basis of signal transduction and how diseases result from dysfunctional regulation. The lab is also interested in rational drug design and the development of biotherapeutic enzymes.
1) development of transiently-stable lipid- and polymer-based carrier systems for targeted drug & gene delivery; 2) development of high-throughput methods for detecting membrane protein activity; 3) development of materials and methods for controlled adsorption and templated protein crystallization
