Profile
Research
My main research focuses on two areas:
The physiology and biophysics of K+ channels and in particular on their regulation by haem-dependent processes. This work involves structure/function studies of haem interaction with K+ channels and an investigation of haem-dependent regulation in arterial smooth muscle.
The regulation of cardiac Ca2+ currents by nitric oxide. This involves examining the different signalling pathways whereby NO can modulate cardiac Ca2+ current. These experiments used the perforated single-electrode voltage-clamp technique.
Both of these projects involve detailed analysis of electrophysiological data which are obtained using single-channel whole-cell patch-clamp and single-electrode voltage-clamp recording. I also develop analysis software and am interested in modelling electrophysiological data.
