Exploring Physics Beyond the Classroom

Learn to Dig Deeper

Passionate about solving real-world problems? From the vast universe to the fundamental atom, Physics at Illinois State University advances knowledge and innovation across all scales of nature. Students engage in cutting-edge research spanning quantum and atomic physics, intense-laser interactions, nanoscience, optics, atro and biophysics - all through hands-on projects guided by dedicated faculty mentors.

Testimonial

Physics at Illinois State University offers a strong education with exceptional opportunities for undergraduates to do research, present their work, and even teach. Because the program is small, undergraduates get opportunities that are usually reserved for graduate students elsewhere. That hands-on experience really sets us apart.
