Dr. Cognato is an Associate Professor of insect systematics and the Director of the A.J. Cook Arthropod Research Collection. He and his students study biodiversity. His research utilizes morphological and molecular characters to reveal the diversity and the historical relationships of insects. This research focuses on bark beetles and these results provide for a better understanding of the distribution, biology, and evolution of local, national, and international forest pests.
