Research interests

I am interested in how a collection of individual behaviors plays a part in group dynamics. Sometimes the group behaves like the sum of many smaller parts (i.e., individuals). But other times, groups display more complex dynamics, not predicted by summing across individuals. These interactions are of particular interest to me. Whether it be in colonies of ants fighting to defend localized resources from interspecific competitors, crabs shoving their way into well defined groups, or queenless ants (my new favorite) sorting within- and among-colony conflicts, my main objective is to determine how individuals make decisions, and how these decisions affect the group. Of course, effects on the group feed back to affect individuals, and the process starts again. Such complexity is the perfect place for me to combine field studies, lab experiments, computer simulations (including social network analysis), more complicated statistics like mixed-effects models, and a bit of proper modeling now and then.
