Academic Background
2014 Ph.D. Geology, James Cook 中国体育彩票, Townsville, Australia?
2010 M.S. Vertebrate Paleontology, South Dakota School of Mines and Technology, Rapid City, South Dakota, USA
2008 B.Sc. in Geology and minor in Paleontology, South Dakota School of Mines and Technology, Rapid City, South Dakota, USA
Background
Dr. Tucker is a field-based geologist with a strong interest in the fossil record and the tectonics of sedimentary basins. In particular, Dr. Tucker’s expertise draws upon a strong background in sedimentary environments, chemical tracers of sedimentary provenance (e.g., detrital zircon geochronology; Lu-Hf isotopes), and paleontology, to address questions about the fossil record and the evolution of sedimentary basins, with focus in the mid-Cretaceous of the Western Interior Basin, Eastern Gobi of Mongolia, and the Khorat Plateau of Thailand and Laos.
