Research Interests


I am interested in the behavioral ecology of arthropods, especially behavior used in social interactions and sexual competition. Traits that function in these contexts provide some of the best examples of rapid diversification and elaboration. Besides the sheer fascination of this topic full of byzantine form and behavior, studying these traits brings insights into the processes of selection, adaptation and divergence.
