The wide range of research interests represented in the department is reflected in its association with a number of campus research institutes and centers: the Center for Astrophysics and Space Science (CASS), the Center for Magnetic Recording Research (CMRR), the Institute for Nonlinear Science (INLS), and the Institute for Pure and Applied Physical Sciences (IPAPS), among others. Interdisciplinary collaborations with colleagues in other natural science and engineering departments, the Scripps Institution of Oceanography, and the School of Medicine, are common. Weekly colloquia and seminars promote social interaction while introducing participants to a wide range of forefront research.
