Dr. Ronald Greeley, Regents’ Professor

Ronald Greeley (1939-2011) was a Regents’ Professor in the School of Earth and Space Exploration (SESE) at Arizona State University (ASU), the Director of the NASA-ASU Regional Planetary Image Facility (RPIF), and Principal Investigator of the Planetary Aeolian Laboratory (PAL) at NASA-Ames Research Center. He had been involved in lunar and planetary studies since 1967. His research focused on understanding planetary surface processes and geologic histories, which involved a combination of spacecraft data analysis, laboratory experiments, and geologic field studies on Earth of features analogous to those observed on the planets.

He was an adored and respected member of the planetary community and a key member of the faculty at Arizona State. He was an incredible mentor and a wonderful friend to everyone who knew him. He is very much missed.
