I studied biology at the University of Giessen in Germany, and in 1998 moved to the UK for a PhD project at the John Innes Centre in Norwich. I started my research career characterising PEPTIDE METHIONINE SULFOXIDE REDUCTASE gene family, which reverses methionine oxidation, a post-translational modification, in Arabidopsis. This project started my interest in environmental stress, and I then continued as a postdoc at the University of Essex to investigate drought and heat stress signalling pathways in Arabidopsis and oilseed rape. In 2006 an EMBO short term fellowship led me to the University of Utrecht to investigate the role of HEAT SHOCK TRANSCRIPTION FACTORS in pathogen responses. This was followed by a BBSRC funded project systems biology project (SABR initiative) where I used gene regulatory network modelling to identify novel drought regulatory genes.
I started my academic career as a Lecturer in 2011 at the University of Essex, to building a research portfolio in drought stress and plant water use. My lab has developed a water use proxy trait for the evaluation of natural variation and genetic mapping of drought response and water use traits, which we have since applied to study natural variation in Brassica crops. More recently we have used evolutionary genomics approach to highlight the role of novel genes in the evolution of terrestrialisation, and to determine the modes of evolution of key anatomical features essential for water uptake and transport in plants.
I moved to the Durham University take up a position as Associate Professor of Plant Molecular Biology in March 2022, where I will continue to work on the integration of plant growth and stress signalling pathways in response to drought stress.

Research Interests

My research focuses on understanding plant stress responses with an emphasis on heat and drought. I use a wide range of approaches to study several different aspects of stress responses and signalling pathways at different levels:
• Transcriptional and post-transcriptional regulation
• Post-translational modifications
• Comparative genomics
• Evolution of genomes and quantitative trait architecture
