The Department of Physics offers courses leading to the degrees of Master of Science and Doctor of Philosophy. There are opportunities for study and research in both experimental and theoretical physics. Areas of specialization include astrophysics and cosmology, atomic and molecular physics, condensed matter physics, elementary particle physics, quantum field theory and string theory, quantum optics, and statistical physics. Through ongoing faculty recruitment efforts the department continues to develop existing active research efforts and expand into new areas. The Ph.D. program is aimed at enabling a student to prepare for and carry out research in physics at the frontier of knowledge. The department encourages entry into doctoral research under the supervision of a faculty member as soon as one has attained sufficient mastery of the fundamental principles and techniques of physics. Depth and breadth within the larger context of contemporary physics are promoted by a flexible set of course requirements.
