Historically, the fields of biology and physics have been fairly far removed from each other as undergraduate disciplines. After all, biology deals with life in its variety and complexity, whereas physics looks for mathematical laws of nature in order to allow detailed predictions about idealized systems. But the past few decades have seen an emergence of a new field – biophysics – that attempts to span the distance between the complexity of life and the simplicity of physical laws. This new and exciting field holds great potential toward solving some of today’s greatest challenges, including how to meet the future demands for energy and food while preserving biological diversity on our planet.

The biophysics program is highly interdisciplinary, providing students with the background and techniques of biology, chemistry and physics necessary to enter this rapidly growing field. A key component of the program is the hands on experience gained in numerous laboratory settings across the disciplines of biology, chemistry and physics, culminating in a senior capstone research experience in the biophysics area. The program’s flexibility is intended to allow students to tailor their experience toward their personal interests, be it in industrial research, engineering, teaching, or health-science. The program’s structure is intended to prepare a student for the rigors of advanced degree programs in biophysics as well as a wide variety of other fields of physics, law, medicine, health sciences, and biotechnology.

The biophysics major requires 24 semester hours of specific physics courses, 16 semester hours of specific chemistry courses, 8 semester hours of specific biology courses, 3 semester hours of a specific mathematics course, and 15 credit hours of natural sciences electives (5 of which must be in physics). To strengthen and broaden the background of all Xavier students, a liberal arts core curriculum consisting of courses in history, literature, foreign language, philosophy, social sciences, fine arts, and theology is also a part of the program. Upon successful completion of the undergraduate program, students receive a Bachelor of Science (B.S.) degree in biophysics.
