Biography
Dr. Ullmann investigates the mechanics of bone fossilization as well as chemical alteration pathways that lead to preservation of soft tissues and biologic molecules in vertebrate fossils. His research integrates cutting-edge techniques from molecular biology, geochemistry, and traditional paleontology to explore how soft tissues and their component molecules, especially proteins, are able to persist in ancient fossils.
After his doctoral work as a National Science Foundation Graduate Research Fellow at Drexel University, Dr. Ullmann served as a Postdoctoral Fellow and then Assistant Professor at Rowan University in Glassboro, New Jersey. He is excited to be expanding paleontology course offerings and research opportunities within UND's School of Geology & Geological Engineering. Starting Spring 2024, he will teach Discovering Dinosaurs and the Real Jurassic Park, and the following academic year he will begin offering additional classes for the Paleontology Concentration of the Geology major.
