After receiving his Ph.D. from UCLA, Dr. Barth was a National Science Foundation Postdoctoral Fellow at the University of Bonn, 1958-59. Before coming to LASP, he worked as a Research Physicist at the Jet Propulsion Laboratory from 1959 to 1965. Dr. Barth was the Director of LASP from 1965 to 1992. He was an Associate Professor from 1965 to 1967 and a Professor in the Department of Astrophysical and Planetary Sciences from 1967 to 2002. Dr. Barth has been a Professor Emeritus at LASP and in the Department of Astrophysical and Planetary Sciences at CU Boulder since 2002.

Between 1962 and 2002, Dr. Barth served as Principal Investigator for eleven missions and experiments. Among these were Mariner 5, Mariner 6 and 7, Mariner 9, OGO-2, 4, 5, and 6, Atmosphere Explorer-C and D, the Solar Mesosphere Explorer, and the Student Nitric Oxide Experiment. He was a Co-Investigator for ultraviolet experiments on Apollo 17, Pioneer Venus, Galileo, and Cassini.

Dr. Barth has served on the NASA Space and Earth Science Advisory Committee (1982-1985), the NASA Advisory Council's Solar System Exploration Committee (1980-1987), and as a Distinguished Visiting Scientist at NASA's Jet Propulsion Laboratory (1995).
