Department Heads and Directors
Gerard P. Kuiper
Gerard P. Kuiper (1905-1973) is considered by many as the father of modern planetary science. In 1960 Kuiper established the Lunar and Planetary Laboratory (LPL), first as part of the Institute of Atmospheric Physics and later as a separate unit at the University of Arizona. In his years at LPL, Kuiper established a group of telescopes in the Santa Catalina Mountains above Tucson; made balloon spectroscopic observations of the Earth’s atmosphere; and conducted observatory site surveys in Hawaii, Mexico, and California. He also studied the atmosphere of Saturn’s moon Titan in 1944, the carbon dioxide atmosphere of Mars in 1948, Uranus’s satellite Miranda in 1948, and Neptune’s satellite Nereid in 1949.
Charles P. Sonett
In 1973, Gerard P. Kuiper (1903-1973), widely considered to be the father of modern planetary astronomy, invited Charles P. Sonett to be his successor as director of the Lunar and Planetary Laboratory and to head the new interdisciplinary Department of Planetary Sciences, chartered that year by the Arizona Board of Regents. As a space exploration pioneer, Sonett was involved in numerous spacecraft programs, including the Pioneer Program, the Explorer Program and the Apollo Program–missions that dramatically advanced our understanding of the solar system, its planets and moons and beyond.
During his term as the second LPL director and first planetary sciences department head (1973-77), Sonett presided over a dramatic expansion. He built research and education programs in solar system science that became internationally recognized. In 1992, Sonett was named a Regents' Professor, the highest academic rank at the UA. Sonett retired in 2003 as a Regents' Professor Emeritus.

Henyey. Dr. Hubbard was appointed Associate Professor at LPL in 1972 and served as Department Head and Director from 1977 to 1981. He is the recipient of many honors, including: election as Fellow of the American Geophysical Union (1991); election as Fellow of the American Association for the Advancement of Science (2003); receipt of the Gerard P. Kuiper Prize in Planetary Sciences (2005). Hubbard contributed to the 2013-2022 Planetary Sciences Decadal Survey of the U.S. National Research Council as a member of the Giant Planet Panel.
Professor Hubbard's research interests include planetary interiors, high pressure physics, structure of rotating planets, stellar structure, occultation theory and observation, turbulence, extrasolar giant planets and brown dwarfs. He has over 200 scientific publications, and was involved in the astronomical discoveries of the Neptune ring arcs, the small Neptune satellite Larissa, and the atmosphere of Pluto. Professor Hubbard was a member of the original proposal team for the Juno Jupiter orbiter mission, and is currently a Juno co-investigator with responsibility for using its gravity measurements to help determine Jupiter’s interior structure and composition.
Laurel L. Wilkening
Cosmochemist Laurel Wilkening began her career at LPL in 1973, joining the faculty as an Associate Professor. Her research focus was comets and meteorites; she was editor of the University of Arizona Press Space Science volume, Comets (1982). Professor Wilkening served as LPL Department Head and Director from 1981-1983 before moving on to other prestigious administrative positions, including service as Dean of the UA Graduate College (1987-1989) and also as Vice President for Research, Vice Provost, and Acting Dean of Sciences. During her scientific career, she served on many national commissions and committees related to the U.S. space program, including terms as Vice Chair of the National Commission on Space, Vice Chair of the Advisory Committee on the Future of the U.S. Space Programs, and Chair of the Space Policy Advisory Board.
From the beginning of her faculty career, Professor Wilkening was instrumental in the development of women's studies at the University of Arizona, teaming with Professor Myra Dinnerstein to advocate for creating an academic department; she served on the Women's Studies Advisory Council, which formed to generate financial and political support for the Women's Studies department. Professor Wilkening endowed The Myra Dinnerstein International Travel Fund for Dissertation Research on Women and made the lead monetary gift in support of the Women's Plaza of Honor. Today, the Department of Gender and Women's Studies offers a B.A. with optional concentrations in Chicana/Latina Studies and Sexualities and Queer Studies concentrations; J.D./M.A. in conjunction with Rogers College of Law; a graduate certificate program and, since 2008, a Ph.D. program in Gender and Women's Studies that is already within the top six nationally.
Professor Wilkening achieved a number of firsts: at the University of Arizona, a she was the first person to serve as Dean of Sciences and first woman to serve as a Vice President. She was also the first woman to serve as Provost at the University of Washington, the first woman to serve as Chancellor at the University of California, Irvine, and the third woman to serve as a Chancellor of a University of California campus.
In 2001, Professor Wilkening was interviewed for the NASA Johnson Space Center Oral History Project.
Eugene H. Levy
Eugene H. Levy graduated with high honors from Rutgers University in 1966 and earned a doctorate in physics in 1971 from the University of Chicago. His research expertise is space and solar physics, planet formation, and planetary observational techniques. Levy began his career at LPL and the University of Arizona in 1975 with an appointment as Assistant Professor of Planetary Sciences.
From 1983-1994, Professor Levy was LPL Department Head and Director; he moved on to serve as Dean of the UA College of Science until 2000, when he became Professor and Provost at Rice University.
Michael J. Drake
Michael J. Drake attended Victoria University (Manchester) where he received a Bachelor of Science degree in Geology in 1967. He earned his Ph.D. in Geology at the University of Oregon in 1972. After a year as a postdoctoral research associate at the Smithsonian Astrophysical Observatory, he migrated to the University of Arizona.
Drake's breadth of research expertise led to his achieving the rank of Professor in the Lunar and Planetary Laboratory (LPL), the Arizona Research Laboratories, and the Department of Geosciences at the University of Arizona. He was appointed Head of the Department of Planetary Sciences and Director of the Lunar and Planetary Laboratory in 1994, a position he held until 2011. He was appointed as Regents’ Professor in 2005. Under his leadership, LPL successfully built and flew a variety of spacecraft instruments including the Imager for Mars Pathfinder, the Descent Imager/Spectral Radiometer (DISR) on Cassini/Huygens, the IMAGE Extreme Ultraviolet Imager, and the Gamma-ray Spectrometer Suite on Mars Odyssey. In addition, LPL scientists were selected as Team Leaders on the Visible and Infrared Mapping Spectrometer on the Cassini mission and the High-Resolution Imaging Science Experiment on Mars Reconnaissance Orbiter. During his tenure, LPL built the Surface Stereo Imager and Robotic Arm cameras and the TEGA instrument on Phoenix, and successfully operated Phoenix on the Martian surface from the University of Arizona campus.
Professor Drake was named a fellow of the Meteoritical Society in 1980, the American Geophysical Union in 2002, and the Geochemical Society in 2002. He was a founding fellow of the Arizona Arts, Sciences and Technology Academy. He served as Vice President then President of the Meteoritical Society from 1997-1998 and the Geochemical Society from 1996-1999. He was awarded the Leonard Medal of the Meteoritical Society in 2004. Asteroid (9022) 1988 PC1 was named Drake in his honor by Carolyn Shoemaker. Professor Drake played a key role in defining the planetary science research priorities of the United States, serving on the NASA Space Science Advisory Committee, the Lunar Exploration Science Working Group and as Chair of the NASA Solar System Exploration Subcommittee, among many other service commitments.
Professor Drake developed the OSIRIS-REx Asteroid Sample Return mission concept. His leadership of the OSIRIS-REx team was instrumental in its success of moving into a selected flight mission project. The scientific goals of the mission are to investigate the possibility of asteroid delivery of prebiotic molecules to Earth and Mars, to connect the meteorite collection to the astronomical asteroid spectral database, to investigate near-Earth resources that may be used by humans going to the Moon and Mars, and to improve our ability to mitigate against devastating near-Earth object impacts. As the mission leader Drake established the OSIRIS-REx guiding philosophy of obtaining excellence at every level, allowing for clear and open communication across all levels of the team, and staying focused on the mission objectives.
