Students in the Department of Physics and Astronomy at the University of New Mexico find themselves immersed in a stimulating atmosphere arising from their exposure to the teaching and research activities of 29 regular faculty members, another several dozen research, adjunct and part-time faculty members, a dozen postdoctoral research associates, and from their interactions with well over 100 undergraduate majors and over 120 graduate students. The atmosphere is enriched by activities of the Center for Quantum Information and Control, the Consortium of the Americas for Interdisciplinary Science, the New Mexico Center for Particle Physics, and the Institute for Astrophysics, which are housed in the department; by the Center for High Technology Materials, in which physicists and engineers are at work on understanding and developing optoelectronic materials and devices with novel properties; by the New Mexico Center for the Spatiotemporal Modeling of Cell Signaling, a collaborative effort that includes physicists, engineers, mathematicians, and biologists to study complex cell signaling networks, and by the collaborative projects the faculty and students in the department carry out with neighboring laboratories such as Sandia National Laboratories, the Los Alamos National Laboratory, the Air Force Research Laboratory, and the National Radio Astronomy Observatory; with local industries, and with institutes, universities and other centers of learning in the USA and elsewhere. Outstanding scientists from all over the world visit the department for periods of a few weeks to as long as a year, while seminars and colloquia feature international experts in their fields each week.
