Juan Roederer

Space Physics

Born in Trieste, Italy, on September 2, 1929, Juan Roederer earned a Ph.D. in physical-mathematical sciences at University of Buenos Aires, Argentina in 1952. From 1953 to 1955 he worked as a research scientist at Werner Heisenberg's Max Planck Institute for Physics in Göttingen, Germany, and from 1959 to 1966 was professor of physics at the University of Buenos Aires. In 1967 he became professor of physics at Denver University, Colorado. In 1977 he was appointed director of the Geophysical Institute at UAF, a post held until 1986; during that time he also served four years as dean of the College of Environmental Sciences. The University of Alaska conferred him Emeritus status in 1993. A visiting staff member of the Los Alamos National Laboratory since 1978, he was chairman of its advisory committee on Earth and Space Sciences from 1983 to 1988. From 1986 to 1992 he served two United States presidents as chairman of the U.S. Arctic Research Commission. Between 1997 and 2003 he was senior adviser to the director of the Abdus Salam International Centre for Theoretical Physics in Trieste, Italy. Roederer’s research fields are space physics, psychoacoustics, science policy and information theory. He conducted pioneering research on solar cosmic rays, on the theory of earth’s radiation belts, neural networks for musical pitch processing, and on the foundations of information theory. He is author of over 250 scientific articles and six books. Roederer is member of the Academies of Sciences of Austria, Argentina and the World Academy of Sciences, and fellow of the AGU, AAAS and IUGG. He is also an accomplished organist and now lives in Boulder, Colorado.
