I am currently an AssociateProfessor in the Department of Physics and Astronomy at the University of Denver. Before joining DU in September of 2006, I did post-doctoral work with the Quantum Sensors Project at the National Institute of Standards and Technology (NIST) in nearby Boulder, CO. I grew up in Albuquerque, New Mexico and earned my B.S. at UC Santa Cruz and my Ph.D. at UC San Diego, working with Frances Hellman.

Experimental condensed matter and materials physics, focusing on understanding order and disorder in novel materials and small structures by probing thermal, electronic and thermoelectric properties. Current projects center on fundamental studies of thermal transport and thermopower in amorphous semiconductor systems, magnetic and superconducting thin films, and nanostructures. Applications of interest range from thermoelectric materials to spintronic devices to gamma-ray detectors for nuclear security.
