William Kurth is a Research Scientist in the Department of Physics and Astronomy at the University of Iowa where he has been a member of the Radio and Plasma Wave group since 1979 upon the completion of his Ph.D. in physics in the same group. His research focuses on plasma waves in space plasmas in planetary magnetospheres and the solar wind as well as solar system radio astronomy. He has done extensive work on plasma waves at Earth and each of the giant gas planets. He has studied auroral kilometric radiation at Earth and nonthermal radio emissions at Jupiter, Saturn, Uranus, and Neptune. He discovered low-frequency heliospheric radio emissions now thought to be generated near the heliopause. He is using recent Voyager observations to measure the electron density in the interstellar medium.
