Bio

Peter uses geospatial analytics to understand how dispersal of plant pathogens affects the risk of disease outbreak at the landscape level. He applies spatio-temporal models to describe the dynamics of plant diseases in space and time with the goal of developing management decisions based on risk assessment and prediction of disease outbreaks. His research results are used to enhance monitoring of disease outbreaks and develop decision support tools in the integrated management of plant diseases. Other interests include exploring research that bridges epidemiology and population genetics.
