The overarching goal of my research is to understand the processes by which natural selection influences the use of space in animals. I integrate the study of neurobiology, animal behavior, and ecology to ask questions ranging from the neurological mechanisms of memory and behavior, to the large-scale effects of movement on avian communities, to the evolution of cognitive spatial processes.
