The department also has smaller research programs in experimental nuclear physics (Cebra) through the STAR collaboration at the Relativistic Heavy Ion Collider (RHIC) at Brookhaven National Laboratory, high energy astrophysics (Ferenc and Tripathi) by doing ground-based gamma-ray astronomy with air cherenkov telescopes CACTUS and MAGIC, and physics education (Potter) through our innovative Physics 7 course which concentrates on interactive learning for biology majors. The Department of Physics also actively participates in the Complexity Sciences Center, headed by Crutchfield. Rundle, a half time Physics faculty member, is the other physics faculty member associated with the center, which also has faculty members in Mathematics, Statistics, Mechanical and Aeronautical Engineering, Geology, Ecology & Evolution and Neurobiology.
