Research
From original ground breaking discoveries, to the development of new and revolutionary technologies, to the decoding of the stock market, physicists have revolutionized the way we live our lives. Our professors and our graduates are an important part of this chain. Many of our professors have also been recognized as superb teachers and have been widely recognized as world-class researchers in their respective fields of expertise.
The research conducted by the professors in the Department of Physics is concentrated in several sub-specialties, including the physics of biological and complex systems, condensed matter physics, photonics, and the physics of geomaterials. Depending upon their choice of program, undergraduate students will have the opportunity to take courses and participate in research projects in these specialized areas.
