Biology

Student Honors Research: 2010 - 2014

Amherst's Biology Department has a long tradition of active research by its faculty and participation of senior majors and other students in this research. Biology majors who enter the Honors Program devote about half of their academic effort during the senior year to research, and the resulting thesis is often the basis of their first scientific publication.
