# Nigel Unwin

Peter Nigel Tripp Unwin FRS is a British scientist at the MRC Laboratory of Molecular Biology, where he was Head of the Neurobiology Division from 1992 until 2008. He is currently also Emeritus Professor of Cell Biology at the Scripps Research Institute.

## Life

Nigel Unwin was born in New Zealand. He was a Ph.D. student in the Department of Metallurgy Cambridge University from 1965–68, and then took a position at the MRC Laboratory of Molecular Biology from 1968 to 1980. He was Professor of Cell Biology at Stanford University from 1980 to 1987. In 1988 he returned to the MRC Laboratory of Molecular Biology, taking also a joint appointment at the Scripps Research Institute.
