LPI is now inviting applications for the Graham Ryder Postdoctoral Fellowship, which honors the accomplishments and legacy of Dr. Graham Ryder. Dr. Ryder was a world-recognized authority on lunar samples and the history of the Moon, and was a staff scientist at the LPI for nearly 20 years. The Ryder Fellowship recognizes and promotes excellence in research for scientists within five years of their doctorate. Ryder Fellows are expected to define their own research direction within the planetary sciences, with an expected emphasis on topics in lunar petrology and geology.
