Plant Biology & Crop Science
I obtained a BSc from the University of Reading and a PhD from the University of East Anglia (John Innes Centre). I was a Postdoctoral Researcher and subsequently a BBSRC David Phillips Research Fellow at the University of York (Centre for Novel Agricultural Products), before I moved to the University of Warwick, where I was an Assistant Professor in the School of Life Sciences. In 2011 I moved to Rothamsted Research, where I am currently the Deputy Head of the Plant Biology and Crop Science Department.
My primarily research interest is in plant lipid metabolism. Lipids are among the largest and most structurally diverse families of chemicals in nature and they have a great many biological functions. Certain classes of lipid form membranes; permeability barriers that define cells and compartmentalise all the biochemical processes within them. Other lipids, namely fats and oils, act as nature’s most energy rich carbon currency, while others still function as signalling molecules (hormones and secondary messengers) controlling growth, development and responses to the environment. In my lab we are interested in understanding how plant lipid metabolism is regulated, what its many functions are, and how this knowledge can be applied for our benefit. This work utilises a range of experimental systems including Arabidopsis thaliana and various brassica crop species.
