Overview Graduate work leading to the PhD degree is offered in the Department of Physics. Students may petition for an MA degree on their way to a PhD. Please note that the department will not consider applications from students who intend to work toward the MA degree only. In certain cases, students may petition for a terminal MA degree. Research is a major part of the PhD program, and research opportunities exist across the full spectrum of theoretical and experimental physics, including astrophysics and cosmology; atomic, molecular and optical physics; biophysics; condensed matter; elementary particles and fields; fusion and plasma; low-temperature physics; mathematical physics; nuclear physics; quantum information; space physics; and statistical mechanics. At the Lawrence Berkeley National Laboratory, extensive opportunities exist for research in astrophysics, elementary particle and nuclear physics, condensed matter physics and materials science, and plasma and nuclear physics. Space physics, interplanetary studies, solar plasma research, physics of the upper atmosphere, and cosmological problems are pursued both in the Physics Department and at the Space Sciences Laboratory.
