“As a professor, I am passionate about not just teaching, but also exchanging ideas with students and guiding them towards their goals.

My new colleagues all seem to enjoy teaching and working with students like I do, so I'm looking forward to working together with everyone. All the natural space on campus makes me feel at home already, and I look forward to getting students outside to learn about their environment.”

Sesterhenn holds a BA in Zoology from Ohio Wesleyan University and a PhD from University of Kentucky.
