Degrees Conferred:
M.S., Ph.D. in Physics (PHYS)

Primary Areas of Faculty Research: Astronomy/astrophysics, biophysics/neuro-physics, computational/theoretical physics, condensed matter/nano-physics, non-linear and quantum optics.

Prerequisites to M.S. and Ph.D. Degree Programs:: Prospective students must satisfy the requirements of the Graduate School as described in this catalog and have the approval of the Graduate Admissions Committee of the Department of Physics. In addition, to be admitted to graduate study in physics without deficiency, candidates should have an undergraduate degree with the equivalent of a 30-hour major in physics including intermediate-level courses in mechanics, electricity and magnetism, quantum physics and thermal physics, and mathematics through differential equations.

Students who present less than the above may be admitted with deficiency dependent on degree track subject to the approval of the department’s Graduate Admissions Committee. Students may eliminate deficiencies while concurrently enrolling in graduate courses, provided prerequisites are met.

While submission of Graduate Record Examination scores is not required for admission, students who have taken the GRE advanced physics test are urged to submit their test scores to the physics department to facilitate advising and placement.
