I am interested in the evolutionary and ecological consequences of how individual animals make decisions. I approach ecological questions from a cognitive perspective, combining theoretical, computational, and empirical work. The two main systems on which I've worked are Anolis lizards and honey bees. Different questions are often best addressed by different kinds of experiments, and I combine work in the lab, in semi-natural settings, and in the field.
