Research Interests

Symbioses between microbes and other organisms play a central role in the ecology and evolution of life on Earth.  Our lab studies the diversity and function of fungal and bacterial symbioses of plants, with a primary focus on ectomycorrhizal fungi.  We use a range of field- and lab-based experimental methods to investigate how symbiont communities are structured and their ecological roles in forest ecosystems worldwide.
