Research Interests
I have two main lines of work underway: One line of research centers on foraging behavior, decision-making and communication in bees. This focus has led me to develop and test theories of foraging behavior and to investigate the evolution of communication systems. I have developed novel techniques for quantifying nectarivore foraging behavior. In one effort, I am investigating how the costs and intakes of foraging are perceived by honey bees and how they use this information to choose among flowers. I use artificial flowers in the laboratory so that bees' energy and time budgets can be manipulated.   The bees' perception of costs and intakes is quantified by using an aspect of their communication dance that changes with foraging profits.  I use this information to understand and predict flower choice. One goal of this work is to better understand the ecological and evolutionary relationships between plants and their pollinators.

I am also studying plant-pollinator interactions in Everglades National Park. We are sampling flower-visiting insects on several permanent sites in each of three Everglades habitats.  We are also sampling honey bees using swarm containers and stem-nesting bees using wooden stem nests.
