Prof James Brown
James Brown researches the evolution of plant diseases to understand how pathogens adapt to plants, both in crops and natural populations, and how this knowledge can be exploited for disease control.
He is currently investigating the role of natural selection in a range of situations including fungicide insensitivity in powdery mildew, trade-offs between resistances to different types of fungal pathogens in cereals, and resistance of ash trees to dieback.
His research relates to the need to produce new crop varieties with elite standards of yield and quality and acceptable, all-round disease resistance.
James’s group studies fungal pathogens of crops, especially powdery mildew of barley and wheat, septoria tritici blotch of wheat and ramularia leaf spot of barley. He also uses computer modelling to investigate the co-evolution of plants and their parasites.
