Research Summary:
Research in the Hawkes Lab is focused on a mechanistic understanding of how plant-microbe interactions affect community and ecosystem processes. We explore how these relationships are influenced by alterations in climate, species invasions, and land use. This research is highly integrative and relies on a wide range of techniques, including DNA-based microbial community analyses, stable isotope biogeochemistry, and large-scale field manipulations.
