Research Statement:
My lab bridges the diverse questions and techniques from ecology, genetics and evolution to understand the dynamic interplay between the ecology and evolution of species interactions.  Specifically, we are trying to answer two related questions: 1) how does genetic variation and evolution within populations shape community patterns and processes?  And, 2) how do ecological interactions among species drive evolution within populations over micro- and macroevolutionary timescales?  Our approach to answering these questions integrates a combination of natural history, lab and field experiments, chemical ecology, quantitative genetics, molecular ecology and evolution, comparative biology and statistics. 

If you are interested in learning more about our research please see our web page ( and always feel free to email or drop in.
