The molecular physiology group was established in the University of Warwick partly as a result of the foundation of the Leicester Warwick Medical School with Warwick offering a four year course to its graduate only entry. I was appointed to the newly established chair of Molecular Physiology in March 2001, having previously been Professor of Physiology (since 1986) in the University of Leicester. I have strong links with The Physiological Society, having served on its Committee for two terms (1985-1990; 1995-1999). From 1996-1999, I acted as Honorary Secretary of the Society. I have served as a member of the UK Life Sciences Committee, which is now the Biosciences Federation.
My research interests centre on the properties and physiological function of ion channels. I am co-author (with the late David Aidley) of a text book Ion Channels: Molecules in Action, published by CUP. Part of my research work has been carried out in collaboration with colleagues in the USA and in Hungary (at the University of Debrecen). I have been visiting professor at Purdue University and at the University of Illinois at Chicago. I was appointed an Honorary Member of the Hungarian Physiological Society in 2001.
I was elected Fellow of the Academy of Medical Sciences in 2003.
