Research interests
I have been interested in fluorescence microscopy since 1989 when I first started to use the ratiometric calcium indicator FURA 2 AM to monitor changes in the intracellular free calcium concentration of cells upon ligand receptor activation. My main interest now is super-resolution microscopy techniques that can be used to quantify the homo- and hetero-oligomerisation state of fluorescing receptor proteins in living cells before and after receptor protein stimulation using drugs which have different potency and efficacy. The weblink below summarises nicely the novel technology that I am particularly interested in which offers a 10x and 100x improvement in resolution and 100x faster image acquisition compared to other super-resolution and confocal techniques which use camera based detectors:
