- Professor, Entomology, College of Agriculture and Life Sciences
I've been very fortunate to have studied many things in many places with many people. Much of my research to date has focused on the biology and ecology of grasshoppers, locusts and Mormon crickets. More recently, I've been given the chance to expand my research program to problems in cotton entomology. It's a pretty unique opportunity, and I am happy to say that the lab is up and running on multiple fronts. Although the emphasis has shifted to cotton research, locust biology and anything else that strikes an interest continues to be fair game in the lab.
