Interested in joining the lab?
We are recruting graduate students to apply for the December 1, 2025 application deadline to join the lab as PhD students for Fall 2026. We are also recruiting UTK undergraduate students to join the lab to work on research projects focusing on moss parent-offspring conflict. This includes the potential for skill building in histology, morphological data collection, molecular systematics, and fieldwork. If our lab seems like it might be a good fit for you, please send an email expressing your interest with your CV/resume and unofficial transcripts attached to Dr. Jessica Budke jbudke@utk.edu
