About the Speaker

Michael Y. Levy was born in New York in 1975. He received the dual B.S. degrees in electrical engineering and physics from Portland State University, Portland, OR, in 2001, and the M.S. and Ph. D degrees in Electrical Engineering from Georgia Institute of Technology, Atlanta, in 2004 and 2008, respectively. His thesis focuses on photovoltaic absorbing media with an intermediate band of electronic states. Currently, he is a U.S. National Science Foundation International Research Fellow being hosted at the Instituto de Energia Solar, Universidad Politecnica de Madrid. His current research focuses on experimental characterization techniques including luminescent spectroscopy and deep-level transient spectroscopy. Michael is the first author of five peer-reviewed journal publications spanning topics in electrical engineering, applied physics, and physics.
