Stephan Friedrich studied physics at the University of Tübingen and the University of Colorado and received his PhD in applied physics from Yale University. He has previously won two R&D 100 awards: one for creating a product to meld mass and gamma-ray spectroscopy, and another for the superconducting tunnel junction x-ray spectrometer. Friedrich currently serves as the deputy group leader for the Rare Event Detection group in the Nuclear & Chemical Sciences Division.
Friedrich’s research interests include the development of high-resolution superconducting x-ray and gamma-ray spectrometers and their application in material science, nuclear physics, astronomy, and national security.
