Two distinguished faculty members of the University of Arizona College of Science have been named 2015 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.

2015 Galileo C​ircle Fellows

John G. Hildebrand
Regents’ Professor of Neuroscience

Regents’ Professor Hildebrand sets the standard for academic excellence at the University of Arizona.  His scientific accomplishments have earned him numerous national and international awards including acceptance into the prestigious National Academy of Sciences and the American Philosophical Society.  In 2014, he was elected to a four-year term as Foreign Secretary of the National Academy of Sciences, a position that has him traveling the world. For 28 years, he led the UA’s Arizona Research Laboratories Division of Neurobiology and Department of Neuroscience.  A goal of Dr. Hildebrand’s research is to discover the fundamental principles and mechanisms common to many or all nervous systems. He does this through studies of insect nervous systems, in particular, olfactory systems.  His work combines anatomical, behavioral, chemical, and neurophysiological methods in a multidisciplinary approach to investigate the organization, physiology, functions, and postembryonic development of the insect nervous system.  He has been an outstanding mentor of graduate students and post-doctoral fellows and has maintained an undergraduate teaching portfolio every year of his tenure at the University of Arizona. 

Christopher K. Walker
Professor of Astronomy
Elizabeth and Keith Hege Galileo Circle Fellow

Professor Walker’s pioneering contributions to the field of TeraHertz (THz) astronomy have led to increased understanding of protostars and the molecular cloud environments in which they form.  He has over 25 years of experience designing, building, and operating leading-edge receiver systems for THz astronomy.  In 1991, he founded the Steward Observatory Radio Astronomy Lab (SORAL), which is now a world leader in the development of innovative sub-millimeter-wave receiver systems.  Professor Walker and his team constructed the world’s first 810 and 345 GHz heterodyne array receivers.  Professor Walker is the Principal Investigator and leader of an international team flying NASA's balloon-borne Stratospheric TeraHertz Observatory (STO) from Antarctica next year. He is also PI of a NASA advanced technology project to develop a suborbital, balloon-borne 10-meter telescope that can be used for astronomy, remote sensing, and telecommunications activities. Professor Walker’s work often takes him to the South Pole, where for over a decade he and his team provided the primary facility instruments for the National Science Foundation’s AST/RO telescope.  He is the recipient of the Millikan Fellowship in Physics at Caltech, the NSF Young Investigator Award, and the United States Antarctica Service Medal.
