Degrees Offered: Ph.D., M.S.

These programs are offered in Durham.

Physics is concerned with the properties of matter and the laws that describe its behavior. As a fundamental science, its discoveries and laws are basic to understanding in nearly all areas of science and technology. Advances in such diverse fields as medical instrumentation, solid state electronics, and space research have relied heavily on the application of basic physical laws and principles.

The mission of the Department of Physics is two-fold: to prepare students for a variety of career opportunities in business, industry, government and education/academia, and to conduct world-class research in various fields, including space and astrophysics, nuclear physics, high-energy physics, gravity, and solid state physics. The department has currently 28 teaching faculty, 11 research faculty, 105 undergraduate students and 60 graduate students. It houses state-of-the-art educational and laboratory facilities; the affiliated UNH Observatory is open to the public.

The Department of Physics offers the degrees of Master of Science and Doctor of Philosophy. Interested students are encouraged to contact the department for further information. More detailed information is also on the physics department web page at www.physics.unh.edu.

Admission Requirements

Applicants to the master of science and doctor of philosophy programs are expected to have a bachelor's degree in science, with at least 24 credits in physics and closely allied fields. Applicants must submit current scores (within five years) from the general test of the Graduate Record Examination (GRE), and from the GRE physics subject test.

Interdisciplinary Research

The department encourages research in areas related to physics or applied physics. If students desire to do research in a field related to physics, special provisions may be made. Contact the department chairperson or graduate adviser for details.
