RESEARCH INTERESTS
I am interested in the processes that drive the distribution of genetic diversity within and among species, with a focus on the contrast between host adaptation to novel and historical selection pressures. I am especially keen on using genomics to understand the mechanisms underlying the evolution of resistance to introduced pathogens.
