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.
Ashley passed her comprehensive exams – congratulations, Ashley!
We managed to keep spirits up and research going over Zoom and strategic time in the lab.
Meg Licht passed her comprehensive exams – congratulations Meg!
We welcome new undergraduate researcher, Selendra Lewis, to the lab.
A fun week hosting students from the Blanding Campus fduring our yearly Native American STEM Mentorship Program at USU. The students especially enjoyed dissecting aphid and psyllid galls.
Meg and Ashley had successful collecting trips in the Midwest and Eastern US.
Welcome new PhD student, Ashley Dederich!
We had a great time hosting 3 students from the Blanding Campus for a week during our yearly Native American STEM Mentorship Program at USU.
Several of our team spent a terrific, productive week in Athens, GA with collaborator Gaelen Burke. We learned so much, and even got out in the field and collected several valuable specimens–thank you Gaelen!
We recruited a new PhD student, Ashley Dederich, from Millsaps College.
Katie Weglarz successfully defended her dissertation–congratulations Katie!!
Welcome undergraduate researchers Brennan Winkler and Aubrey Gunnell.
