His background is in primarily experimental cosmology - in particular designing and building new types of instruments for measuring signals from the most distant objects in the universe. However, he has broad interests that include solid state physics, atmospheric science and quantum communications and cryoptography. He particularily enjoys the opportunity to pursue interdisciplinary projects within the ASU community as well as collaborating with researchers at other universities and research institutions such as Caltech/JPL, University of Pennsylvania, Columbia University, NIST boulder, Cardiff University (UK) and the Neel Institute and IRAM observatory (France).
