Research Description

My research is centred on cellular and molecular biophysics. Our work can be divided into several areas. First, we aim to understand the molecular composition, pharmacology and physiological role of potassium channels. We are currently focusing our efforts on calcium-activated potassium channels (channels that open in response to an increase in intracellular calcium). Mammalian genes have been identified for several of these proteins including those producing large, small and intermediate conductance channels. A major challenge in this area is to be able to understand the properties of native channels by studying their cloned counterparts. A second theme for my laboratory is developing the use of scanning ion conductance microscopy.  We collaborate with groups both at Imperial (Professor Yuri Korchev) and Cambridge (Professor David Klenerman) in the application of this technique.  Finally, we are using biophysical,  electrophysiological and systems modelling techniques to examine disease and health, in epithelial cells in collaboration with Paola Vergani, Nick Simmonds and Vivek Dua.
