The scope of our interests is broad, extending from molecular biology and biochemistry through cell biology, physiology, neurobiology and behavior, to evolutionary biology and ecology. In the classroom and the laboratory, our students experience the excitement of exploring what’s known and, more importantly, the questions that remain in these dynamic disciplines.  Within the context of the Williams College liberal arts experience, the Biology curriculum creates a potent intellectual mix that equips our majors for success in many different areas after graduation.
