Current Research

The Genomics of Plants, Pathogens, and Pests (GP3) lab uses methods from molecular biology, landscape ecology, population genetics/genomics, and geographic information systems to address issues in wildlife management (yes, plants are wildlife). Often my research looks at spread risk of disease from the perspective of the host. This has included using landscape genetics to understand animal movement to predict raccoon rabies, and chronic wasting disease spread, to identifying genetic variation that may be linked to lodgepole pine susceptibility in the mountain pine beetle system.

Currently I am working on community genomics in pine-pathogen systems. While we can garner considerable information studying species in isolation, we need to examine species as a community to better understand host-pathogen systems. Using methods from population genomics and landscape ecology my lab is investigating the mountain pine beetle and western-gall rust systems to better understand what genetic factors contribute to pathogenicity and host-pine susceptibility. We will use these data to develop risk maps across the relevant ranges of the species which can be used to develop additional research questions, and for making management decisions.

I am seeking potential graduate/undergraduate students to join the lab.
