The Physics Department exhibits exceptional strength in several areas. We invite applications from able students interested in experimental and theoretical condensed matter physics, in structural biophysics and protein dynamics and function, and in cosmology, relativistic astrophysics, and gravitational-wave/multimessenger astronomy. The primary goal of our graduate education is the training of creative research scientists. Our research in gravitational physics is in several areas: In gravitational-wave astronomy, we play a leading role in LIGO, extracting signals of gravitational-waves from the coalescence of binary neutron stars and black holes, as well as searching for electromagnetic counterparts, and in the use of pulsars to measure gravitation waves from supermassive black holes. In relativistic astrophysics we have established limits on the spin and mass of rotating neutron stars, and develop computational techniques to model merging stars. Astronomy efforts include studying early galaxy formation and evolution, and the phenomenology of neutron stars and white dwarfs. Experimental and theoretical work in condensed matter physics is focused on quantum materials, including quantum transport phenomena, superconductivity, magnetism, and novel states of matter.
