Maryville College Senior Study

Department of Biology


Students in Biology conduct a two-semester project involving independent research under the guidance of a faculty advisor. The project culminates in a formal thesis, and the projects of Dr. Crain's students are linked below. Also, many exceptional senior study projects are linked to the Maryville College Undergraduate Research Website.
