Physics has always remained and still is at the center of science and technology. The laws of physics that are reached through observations and careful experimentation find applications from the subatomic particles to the astronomic formations such as stars and galaxies.
On the other hand, design of advanced technology materials, fabrication of semiconductor devices, the development of optical communication systems have all evolved as applications of physics. Our department has both theoretical and experimental research activites. Quantum information theory, gravitation and condensed matter physics are among our theoretical research interests.
On the experimental research side, we have three advanced laboratories where we focus on solid state lasers, optoelectronic and nano-photonic materials and devices. Our M. S. Program aims at teaching fundamental physics at a high level and coupling this knowledge with a research experience in either theoretical or applied physics depending on the interests of the student.

Independent research towards M.S. degree.
Provides hands-on teaching experience to graduate students in undergraduate courses. Reinforces students' understanding of basic concepts and allows them to communicate and apply their knowledge of the subject matter.
This is a writing course specifically designed to improve academic writing skills as well as critical reading and thinking. The course objectives will be met through extensive reading, writing and discussion both in and out of class. Student performance will be assessed and graded by Satisfactory/Unsatisfactory.
