Biography

My research seeks to understand the mechanisms which produce and maintain variation both within and between species and how this variation ultimately affects the evolution of natural populations. I am particularly interested in variation in insect behavioral phenotypes as they relate to plant-insect interactions. I use approaches in behavioral ecology, ecology, population genetics, and phylogenetics to understand how traits important for these interactions are partitioned in space and time, and how this mosaic affects speciation and biodiversity. My current research is aimed at understanding variation in locust behavioral and nutritional ecology and the drivers of of locust swarming behavior, in an effort to improve locust management and global food security.
