Ralph Milliken is an Associate Professor in the Department of Earth, Environmental, and Planetary Sciences at Brown University. His research focuses on planetary surface geology, remote sensing techniques, and the role of water in solar system evolution. He is a science team member for NASA's Mars Curiosity rover, Japan's Hayabusa2 mission, and NASA's OSIRIS-REx mission, contributing to studies of Mars, asteroids, and lunar materials.
Key research interests include reflectance spectroscopy of planetary materials, sedimentary rock records on Mars, and compositional analysis of returned asteroid samples. He investigates aqueous processes on asteroids and Mars, using laboratory experiments and spacecraft data. His work bridges field geology, planetary science, and analytical chemistry to address questions about planetary habitability and surface evolution.
Dr. Milliken's affiliations include the Brown University Department and collaborations with NASA missions. He has pioneered methodologies for interpreting spectral data from planetary surfaces, with a focus on water-related minerals and volatile compounds. His recent projects include analyzing samples from asteroid Bennu and Ryugu, advancing understanding of carbonaceous asteroids and their parent bodies.
His research also addresses space weathering effects on spectral signatures, lunar pyroclast volatile content, and Martian chloride salt distribution. He collaborates internationally to integrate rover-based observations with orbital data, enhancing models of planetary surface processes.
