There is a constant struggle between plants and their parasites: as plants evolve to become resistant to disease, parasites evolve to overcome that resistance. Consequently, crops in agriculture are exposed to a constantly changing population of different genotypes and species of parasites.
My group's research relates to the need to produce new crop varieties with elite standards of yield and quality and acceptable, all-round disease resistance. Much of our research concerns trade-offs between responses to different diseases and between disease resistance and other desirable traits, while we also research processes by which plants and parasites coevolve to become adapted to one another.
We work on several diseases, as appropriate for the research in question. Most of our work is on fungal pathogens of cereals, especially powdery mildew of barley and wheat, septoria tritici blotch of wheat and ramularia leaf spot of barley. Our research on coevolution uses of mathematical and computer modelling.
