Dr. Ben Passey has been promoted to associate professor with tenure in Earth & Planetary Sciences. Ben skillfully teaches at all levels in our E&PS programs and runs a thriving research group. In particular, since arriving at Hopkins, he has made technical breakthroughs in stable-isotope geochemistry that have obstructed the field for decades. He has exploited and applied the new techniques to problems in paleoclimate, paleoecology, and paleoaltimetry. Ben occupies the forefront of the field of stable-isotope geochemistry, and has ascended to become a leading authority on carbonate clumped-isotope geochemistry.
