Research Interests

Research in my group at EMR focusses on understanding the genetic basis of interactions between plants and microbes. Key questions that we are addressing in the lab are focussed around understanding at a mechanistic level how plants defend themselves against pathogen attack and over what timescales these interactions occur. I also have an interest in the application of population genomics, using DNA sequence variation as a tool to understand the functional importance of different classes of pathogenicity genes. There are several ongoing BBSRC projects in this area accounting for the vast majority of research in the lab, often funded in collaboration with the international horticulture industry. The group works both in the laboratory and as bioinformaticians, with a particular interest in the analysis of data from large scale sequencing projects. The objective of most of our work is to provide scientific knowledge to underpin the horticultural industry through pre-breeding and development of novel pathogen control strategies.
