Career

2006 – (Present) – Royal Society University Research Fellow and Professor of Population Biology, University of Sheffield
2004 – 2006 - Royal Society University Research Fellow, University of Oxford
2002 – 2004 – Departmental Lecturer, University of Oxford

Key Research Interests

My research focuses on modelling population and community dynamics. I am particularly interested in large scale population dynamics, although have a range of interests, including:

  • Plant population ecology, modelling plant populations, modelling weed populations.
  • Evolutionary ecology, phylogenetic comparative methodology and its application to ecological problems.
  • Theoretical ecology, statistical methodology.

Professional Activities

Founding Editor, Methods in Ecology & Evolution (2009 - present)
Senior Editor, Journal of Applied Ecology
NERC Peer Review Panel (2004-2006)

Teaching

At Level 1 I lecture for APS121 (evolution) and at Level 3 I lecture for APS342 (Evolutionary Ecology).

At level 3 I teach on a 10 day residential course in Borneo (APS 306) and I supervise projects (APS330) on herbivore-plant interactions, spatial ecology and plant population dynamics, usually field-based.

I have supervised Level 4 projects on conservation, macroecology and evolution.
