Research Statement


I study how bacterial pathogens evolve and spread in plant host populations, and how hosts in turn evolve resistance. My current work aims to elucidate the genetic and population-level mechanisms that prevent the emergence of epidemics. My research touches upon several disciplines within the Biological Sciences including population genetics, microbial and plant genomics and classical microbiology.
