Interests:

Research on epidemiology, modelling, forecasting, diagnosis and control of diseases of arable crops (especially winter oilseed rape, winter wheat, winter barley). Mechanisms and models of development of disease epidemics (spore dispersal, spore germination, infection, latent period, incubation period, sporulation) in relation to environment (rainfall, temperature, leaf wetness). Diagnosis of symptomless and complex infections by mycological and molecular methods. Epidemiology in relation to genetics of host-pathogen interactions. Rational disease control strategies in arable crops by breeding for durable disease resistance and optimising fungicide use. Forecasting risks of severe disease epidemics (e.g. web-based interactive forecast for winter oilseed rape light leaf spot), both now and under predicted climate change.
