Research interests

Our research is focused on understanding the mechanism of leaf development. In particular, we are interested in the interplay of cell growth and division, how these parameters are integrated into the developmental program controlling leaf structure, and the impact the resultant internal cellular architecture has on leaf function- particularly photosynthesis and water-use efficiency.

We take an integrated systems approach, using experimental data derived from advanced imaging, biochemistry and physiology to inform computational models, which we then use to develop testable hypotheses on how structure relates to function, utilising a range of genetic and experimental approaches to alter specific elements of the modelled system.

Over recent years we have developed a keen interest in guard cells, working closely with Julie Gray to investigate how cell wall structure sets the limits for stomatal function and, thus, gas exchange in leaves. This work extends to seeking to understand how stomatal and mesophyll differentiation are co-ordinated, how mesophyll air space is formed, and the control of mesophyll cell shape and separation.

We have a long-standing interest in the earliest phases of leaf initiation and development, including the link between metabolism and development, leading us to projects aimed at elucidating the mechanism underpinning the switch from quiescence to growth in dormant buds.

These projects have allowed us to form valuable collaborations with colleagues around the globe, notably on rice leaf development, as well as the potential translation of our research into agriculture via commercial breeders and UK levy boards.

Teaching activities

I am a developmental biologist. This involves the study of how something apparently simple (a cell) becomes something incredibly complicated (a mature, multicellular organism) in a robust and reproducible fashion. My interest is in plant development, but one of the lessons of the past decades has been how developmental concepts can be applied across the whole of biology, and it is understanding these unifying (and yet distinctive) approaches to solving common developmental problems that underpin my teaching (and my research).

I currently teach on the following modules:

  • APS137 Plant Physiology, Reproduction & Growth (module co-ordinator)
  • APS135 Level 1 Tutorials
  • APS222 Level 2 Tutorials
  • APS355 Future Plants: From laboratory to field
  • APS331 Level 3 Dissertations
  • APS345 Level 3 Projects
  • APS402 Level 4 Dissertations
  • APS406 Level 4 Projects
  • APS6602 MRes Literature Reviews
  • APS609 MRes Research Projects
  • APS6623 Special issues in Global Food Security 
  • APS6624 Crop science, biotechnology & breeding (module co-ordinator)
