Research Area
My lab works on Environmental Control of Plant Growth and Development. We are striving to understand how molecular pathways integrate light and temperature signals. The lab is also wants to determine how light activated pathways control carbon assimilation and resource partitioning in plants.

Background
Current Projects
PHYTOCAL: Phytochrome Control of Resource Allocation and Growth in Arabidopsis and in Brassicaceae crops
Collaborators: Professor Mark Stitt (Director Max Planck Institute of Molecular Plant Physiology, Golm, Germany); Professor Jennifer Nemhauser (University of Washington, WA, USA)
For plants, light is a signal that carries information about the environment, and a source of energy for photosynthesis. PHYTOCAL focuses on the interaction between phytochrome signalling and photosynthesis, and seeks to understand fundamental processes that make carbon (C) and nitrogen (N) resources available for plant growth. These unexplored connections underlie biomass production and plasticity, which contribute significantly to yield variability in the field.

Modelling Light Control of Development
Collaborators: Associate Professor Enamul Huq (University of Texas at Austin); Dr Ramon Grima (University of Edinburgh)
Plant development is strongly influenced by external light cues, yet we know very little of how this is mediated at a molecular level. This BBSRC funded project seeks to determine how phytochrome light receptor signalling connects with the developmental pathways to control plant architecture.
Novel candidates for environmental control of photosynthesis
Collaborator: Dr Gabriela Toledo-Ortiz (University of Lancaster)
This Leverhulme Trust funded aims to understand the molecular machinery through which phytochromes control chloroplast protein abundance.
Predictive Plant
Collaborators: EPS PI’s including Professor Mat Williams (Geosciences, University of Edinburgh), Dr Alistair McCormick (Biological Sciences, University of Edinburgh)
This SULSA-supported multidisciplinary project aims to build upon our expertise in climate change, environmental signalling, and modelling to provide an integrated platform to predict plant responses to a changing environment.
