Position

Associate Professor of Geology, Department of Geology, Appalachian State University

Director, McKinney Geology Teaching Museum, Appalachian State University

Research Associate, New Mexico Museum of Natural History & Science, Albuquerque

Research Associate, North Carolina Museum of Science and Nature, Raleigh

Citizenship: U.S. Citizen by birth (Hamilton, OH)

Education

            Ph.D.    Earth & Planetary Sciences University of New Mexico 2001 (3.99 GPA)

M.S.     Earth & Planetary Sciences University of New Mexico 1997 (3.74 GPA)

            B.S.      Geology summa cum laude Denison University, Granville, Ohio 1993 (3.83 GPA)

Dissertation: The microvertebrate record of the Upper Triassic (Carnian) lower Chinle Group, southwestern U.S.A. and the early evolution of dinosaurs (465 pp)

Thesis: Litho- and biostratigraphy of the lower Chinle Group, east-central Arizona and west-central New Mexico, with a description of a new theropod (Dinosauria:Theropoda) from the Bluewater Creek Formation (278 pp.)

Research Interests

            I am interested in field-oriented, specimen-based microvertebrate studies in vertebrate biostratigraphy, evolution, and systematics especially the early evolution of dinosaurs as revealed by Triassic-Jurassic paleontology, biostratigraphy and biochronology. Presently I am engaged in multiple Upper Triassic micro- and macrovertebrate projects across North America. A secondary interest involves using scanning electron microscopy (SEM) to investigate microvertebrate taxonomy and evolution throughout the Mesozoic.
