RESEARCH INTERESTS

I joined the Shefferson lab in the spring of 2009. My primary focus is on
ectomycorrhizal fungi and modeling the role of partner  choice in maintaining
diverse fungal symbiont communities.  I utilize a combination of computer based
modeling, greenhouse/field experimentation, and DNA techniques in my research.
For my dissertation, I developed a economics-based symbiont simulation model,
and now I am perfoming experiments to test the predictions of that model.  I am
also interested in the evolutionary history of host specificity in mycorrhizal
relationships, developing models of group selection, as well as the ecological and
evolutionary roles of common mycorrhizal networks.  I also work with terrestrial
orchids and their fungal symbionts.
