Dr. Frederick W. Van Keuls is a research engineer at the National Aeronautics and Space Administration's Glenn Research Center at Lewis Field in Cleveland, Ohio. His research interests are designing, fabricating, and testing high-temperature superconducting and thin-film ferroelectric tunable microwave components, including frequency-agile filters, tunable local oscillators, and phase shifters.

Dr. Van Keuls earned his bachelor’s degree summa cum laude in physics and mathematics from Ohio State University in 1985. He earned master’s and doctoral degrees in physics from Cornell University in 1987 and 1992, respectively. His thesis work was on nuclear magnetic resonance (NMR) in 3He films at low temperatures. At Cornell, he was an instructor for electronics courses and a post-doctoral researcher studying 4He films in porous media. From 1993 to 1996, he investigated the electronic properties of two-dimensional gallium arsenide (GaAs) and aluminum gallium arsenide (AlGaAs) heterostructures as a research associate at Case Western University. Dr. Van Keuls has coauthored over 70 publications. He is a member of the American Physical Society and the Institute of Electrical and Electronics Engineers (IEEE). He joined the NASA Glenn Communications Technology Division as a National Research Council (NRC) Research Associate in 1996.
