Physics is the study of matter and energy, from the smallest scale, as in the study of elementary particles, to the largest, as in the study of the formation and evolution of stars and galaxies. In this sense, physics is the science that underlies all other sciences. Physicists tend to view themselves as problem solvers, especially those problems that can be couched in mathematical terms. Physics students are trained to solve complex problems by learning to analyze complex relationships in mathematical terms. Because of a broad-based and flexible problem solving background, physics graduates find employment in a wide variety of fields, some of which are not directly associated with physics.

The department of physics offers a program leading to the B.S. in physics from Purdue University. In addition, the department offers courses for non-majors in physics and astronomy. A M.S. program is also offered, and qualified students can pursue a Ph.D. in areas where a program has been arranged with Purdue, West Lafayette.

Faculty in the department conduct research in several disciplines of physics, with especially strong programs in magnetic resonance based biophysics, nonlinear and quantum optics, and materials physics. Student participation in research is welcomed and encouraged.

Students majoring in physics consolidate their undergraduate studies by putting what they have learnt to use in a capstone experience in one of the department's research labs. Each student is expected to join a faculty member's research group and participate in a project that provides experience in a professional setting.
