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.
