BSc, Nottingham; PhD 1991, Liverpool.
Reader in Ecology
School of Biology

Background: My research career began at the University of Liverpool where I completed my PhD and first postdoctoral position. I then had a spell at the NERC Centre for Ecology and Hydrology in Oxford before returning to Liverpool with a 5-year NERC Advanced Fellowship. I moved to Leeds in 2002 with a 5-year Leeds University Research Fellowship.
