Research statement

Symbioses between microbes and other organisms play a central role in the ecology and evolution of life on Earth. My lab studies the diversity and function of fungal and bacterial communities in a wide range of ecosystems, particularly those forming belowground symbioses with plants. We use both field- and lab-based experimental methods to investigate how microbial communities are structured and their ecological roles in forest ecosystems worldwide.

Teaching statement

In teaching, I strive to expose students to a variety of different learning opportunities, ranging from lectures and primary literature discussions to field- and laboratory-based research. My teaching philosophy includes: 1) providing opportunities for students to directly participate in the process of science, 2) stressing the importance of critical and quantitative thinking, 3) rooting knowledge in history, while at the same time stressing modern issues at the cutting edge of biology, and 4) sharing my deep enthusiasm for the diversity of life on earth.
