 Research Interests

Walker’s research focuses on the impacts of climate change and disturbance from wildfires on tundra and boreal forest ecosystems. She has experience in fire ecology and using dendrochronology techniques to assess climate change impacts on ecosystem resilience and post-fire succession. Dr. Walker is currently working on the NASA Arctic Boreal Research project to study severe fires and the loss of old carbon from boreal forest and arctic tundra soils.
