People



Dr. Xiao is a geobiologist that studies early animal life from all over the world. His work has illustrated the extraordinary preservation of fossil cells and continues to study the early evolution of some of the most bizarre creatures to ever have lived.
Shuhai received his PhD degree from Harvard University. He taught three years at Tulane University before joining Virginia Tech in 2003. He is interested in biological and environmental evolution in the Proterozoic Eon (2500-540 Ma).

Dr. Nesbitt is a vertebrate paleontologist interested in terrestrial vertebrate evolution during Earth’s great transitions. Particularly, Sterling studies the rise of reptiles (archosaurs and their relatives) following the end-Permian extinction.
Sterling received a BA in Integrative Biology from the University of California, Berkeley, a PhD in Geosciences from Columbia University and has conducted postdoctoral projects at The University of Texas at Austin, University of Washington, and the Field Museum of Natural History.

Dr. Stocker is a vertebrate paleontologist focusing on the evolutionary history of reptiles. Michelle splits her research between Triassic archosauromorphs and Paleogene reptiles, as well as the evolution of extant fossorial reptiles called amphisbaenians.
Michelle received a BS in Geological Sciences from the University of Michigan, a MS in Geosciences from the University of Iowa, and a PhD in Geological Sciences from The University of Texas at Austin.

Rachel Reid
Dr. Reid is a paleoecologist interested in how disturbances, such as climate and environmental change, impact species, ecosystems, and their interactions over a range of timescales. Rachel brings an interdisciplinary approach to her research, incorporating viewpoints, tools, and data from geology, ecology, and archaeology, using stable isotope geochemistry as a central methodological tool.
Rachel received a BA in Geology from Carleton College, an MS and PhD in Earth Sciences from The University of California Santa Cruz, and conducted postdoctoral research at Washington University in St. Louis.

Vicki Yarborough is a paleontology lab manager and vertebrate fossil preparator focusing on Triassic archosauromorphs and dinosaurs. Besides carefully exposing specimens from rock, Vicki develops custom archival specimen storage housings along with support jackets for use during preparation. She trains and helps students and volunteers prepare and conserve specimens for CT (Computed Tomography) scanning and research.
Vicki received a Bachelors in Fine Art from the University of Texas at Austin, and a Foundation degree from the Wimbledon School of Art in London, England.

Annamarie is a vertebrate fossil and museum specimen preparator. Extant or extinct, squishy or mineralized, she works to get whatever specimen research-ready. Before VT, Annamarie has prepared specimens for The Field Museum, Chicago Academy of Sciences/Peggy Notebaert Nature Museum, Flint Creek Wildlife Rehabilitation, and most recently, the Badlands Dinosaur Museum.
Annamarie has a BA in English from Kalamazoo College, Michigan

Mariah Green is the Museum and Collections Manager at the Museum of Geosciences. Mariah's MS thesis applied 2D and 3D imaging techniques to evaluate and measure bite force in recent and extinct early Paleocene mammals.
Mariah earned a BS in Earth Science from Northeastern Illinois University in Chicago, Illinois, and earned an MS in Museum and Field Studies with a paleontology specialization from the University of Colorado Boulder.
