Description of research activities: Currently our research focused on the identification of protein-protein interactions by quantitative Förster resonance energy transfer (FRET) measurements as well as by florescence intensity ratio (FIR) analysis in live cells. We are interested in G-protein Coupled Receptor (GPCR) dimerization, and effects of post-translational modifications and ligand interactions on receptor dimerization.
