I joined the Tree-Microbe Interactions group via an AgreenSkills fellowship to study the evolution of poplar rust (Melampsora larici-populina) in response to human-bred disease resistance in poplar plantations. Prior to my arrive at INRA, my research centered on the interaction of tanoak, a unique California native tree, with the recently emerged disease sudden oak death. This system allowed me to study host-pathogen interactions, invasion biology, and emergent diseases using methods that range from classical quantitative genetics to next-generation sequencing, genomics, and transcriptomics. Throughout, my focus has been the management of natural systems with an eye toward evolutionary dynamics.
