I have always been interested the development of plants and have covered many aspects of plant development during my research career. Firstly I completed my PhD at Rothamsted Research under the supervision of Peter Hedden, Steve Thomas and Andy Phillips where I identified early GA regulated genes, one of which was identified as the GA receptor GID1. I followed up my research on GA by moving to another phytohormone, this time investigating ABA and dormancy in CSIRO, Canberra. After a short position back at Rothamsted Research, where I was following up lines of research founded during my PhD, I moved to the University of Edinburgh where I was involved in a large multidisciplinary project researching the effects of the circadian clock and temperature on plant development. When I moved to the Sainsbury Laboratory Cambridge University, I became involved in lab management. I was the Paszkowski Lab Manager whilst simultaneously researching epigenetic effects on plant development and stress induced transposable elements.


Research Interests

I now work in the Jones group as Lab Manager and Research Associate. The importance of the phytohormone gibberellin for plant growth and development is well recognised. Understanding where and how GA is distributed is the first step to understanding how GA signalling leads to such a diverse range of responses. Using live cell imaging the Jones group have demonstrated gradients of GA in developing tissues. I am interested in how these spatiotemporal patterns of GA arise.
