Jay Ague

Jay Ague is the Henry Barnard Davis Memorial Professor of Earth & Planetary Sciences at Yale University, with a dual role as Curator-in-Charge of Mineralogy and Meteoritics at the Yale Peabody Museum. He specializes in metamorphic petrology, fluid dynamics in Earth’s crust, and carbon cycle processes. His research integrates fieldwork, geochemical analysis, and numerical modeling to study metamorphic rocks, subduction zone processes, and crustal fluid flow.

Education: Ph.D., Geology, University of California, Berkeley; M.S. and B.S., Geology, Wayne State University. Honorary Master of Arts (Privatum), Yale University.

Research focuses on ultrahigh-temperature metamorphism (e.g., Connecticut’s first UHT locality), carbon fluxes in orogens, and subduction zone geochemistry. He leads expeditions globally, including Greece, New Zealand, and the Mediterranean. Current projects include UHT garnet exsolution studies and carbonation-decarbonation mechanisms in subduction zones.

Publications span over 100 peer-reviewed articles, emphasizing metamorphic fluid flow, element mobility, and carbon cycling. He serves as Associate Editor of the American Journal of Science and editorial boards of Chemical Geology and Journal of Metamorphic Geology.

Teaching includes courses on petrology, metamorphic processes, and natural resource sustainability. His software contributions (e.g., MATLAB tools for pseudosection analysis) aid thermodynamic modeling in metamorphic studies.
