Welcome to the von Dohlen research group at the Department of Biology, Utah State University, Logan, Utah!

Our current research centers on the evolution of sap-feeding insects and their bacterial endosymbionts, evolution of gall formation and life cycles in sap-feeding insects, and molecular phylogenetics of insects.

The witch-hazel shown above is a host plant of aphids I studied as a graduate student. Witch-hazel aphids form galls on their host plants and have fascinating, host-alternating life cycles. Both aphids and  witch-hazels have  intriguing, disjunct distributions in eastern North America and eastern Asia. How and when such disjunctions developed in aphids has been another subject of our research.
