Professor David Colquhoun, FRS, held the established (A.J. Clark) chair of Pharmacology at UCL, and was the Hon. Director of the Wellcome Laboratory for Molecular Pharmacology. In October 2004, he became a Research Fellow. Like many previous holders of the chair (in particular, A.J. Clark, J.H. Gaddum, H.O. Schild and J.W. Black) his interests are in quantitative analysis of receptor mechanisms.
He graduated from Leeds with a BSc and then went to Edinburgh to work for a PhD. After doing research at University College from 1964-69 on immunological problems and completing a book on statistics, he went to Yale University to work on nerve conduction. After returning from the USA he eventually returned to the Pharmacology Department at UCL in 1979, and has worked on single ion channel mechanisms since then. In 2004, he was made an Honorary Fellow of University College London.
