Denton S. Ebel

Dr. Ebel is a geologist specializing in meteorites: pieces of planets and "left-overs" from the formation of the solar system. The distant, metal resource-rich asteroid belt is his field area. He develops thermodynamic models describing the outcomes of condensation, evaporation, and crystallization processes. Dr. Ebel is a leader in combining electron beam image analysis of surface chemistry (2D) with x-ray CAT-scan 3-dimensional imaging of extraterrestrial samples that yield clues to the origin of the solar system. His group has analyzed data from the MESSENGER mission to Mercury, comet samples from the Stardust mission, and the geochemistry of samples from the Cretaceous/Paleogene boundary. Dr. Ebel is PI of the AMNH/CUNY Physical Sciences REU program, faculty of the AMNH Master of Arts in Teaching Earth Sci. Residency Program, and a science Co-PI on the OpenSpace( project.
