Galileo Circle Fellows

Three distinguished faculty members of the University of Arizona College of Science have been named 2018 Galileo Circle Fellows, one of the highest honors bestowed upon faculty in the College.

These awards, established through the generosity of Galileo Circle members, recognize outstanding accomplishments in academic scholarship.  Each Fellow receives $5,000 and lifetime membership in the Galileo Circle.

Galileo Circle Fellows are the epitome of the academic scholar, with a deep understanding over a broad range of science, a willingness to think in a truly interdisciplinary way, and an ability to inspire colleagues and students alike.

2018 Galileo C​ircle Fellows

S. Scott Saavedra
Professor, Department of Chemistry and Biochemistry

Scott has been a member of the University of Arizona faculty since 1991, and has led numerous interdisciplinary research projects spanning the fields of analytical/physical chemistry, materials science, optics and spectroscopy, biophysics, and measurement science, with an emphasis on development of methods to characterize thin films and interfaces. The research activities of his group have been supported by grants from NIH, NSF, DOE and private foundations, and have been published in over 130 journal articles and book chapters. Scott is best known for his development of spectroscopic platforms that have provided key insights into the structure and function of artificial biomolecular assemblies and solar energy conversion systems. The seminal publications by Scott’s group focused on the determination of molecular orientation in protein and proteo-lipid assemblies and thin films of energy-converting molecules, and how orientation affects functional properties such as charge transfer, are acknowledged as the definitive work in both the biointerface and energy conversion communities. This type of impact in disparate disciplines is unusual in today’s compartmentalized scientific culture.

Adam Showman
Professor, Department of Lunar and Planetary Laboratory

Dr. Showman is a Professor in the Department of Planetary Sciences and the Lunar and Planetary Laboratory at the University of Arizona. He obtained his Ph.D. in 1999 from the California Institute of Technology, and then was a National Research Council Fellow at the NASA Ames Research Center before starting as a faculty member at the University of Arizona in 2001. Dr. Showman’s research covers broad areas of atmospheric and interior dynamics of planets. Dr. Showman is best known for his work pioneering our understanding of the atmospheric circulation of gas-giant exoplanets (the “hot Jupiters”), which are Jupiter-mass planets that orbit extremely close to their stars. Dr. Showman has also been the leader in understanding the atmospheric circulation of brown dwarfs. He has also made major contributions to a diverse range of other topics, including (1) understanding the processes controlling the zonal jet streams and cloud banding of Jupiter, Saturn, Uranus, and Neptune; (2) the atmospheric dynamics of smaller planets, including terrestrial planets; and (3) the tectonics, orbital, and thermal evolution of satellites in the outer solar system, including Jupiter’s moons Io, Europa, Ganymede, and Callisto and Saturn’s moons Titan and Enceladus. Dr. Showman enjoys mentoring and advising younger scientists; he has worked with over 20 graduate students, and has been primary Ph.D. advisor to eleven graduate students and five postdoctoral scholars. These group members have subsequently gone on to a variety of prestigious positions, including faculty positions at institutions such as U.C. Santa Cruz, University of Michigan, Hampton University, and Oxford University.
