Mary Higby Schweitzer is a vertebrate paleontologist and evolutionary biologist who specializes in recovery of biomolecules from ancient fossils, including dinosaurs. She is a tenured full professor in the Dept. of Biological Sciences at North Carolina State University, a Curator of Paleontology and the NC Museum of Natural Sciences, and Research Curator at the Museum of the Rockies. Schweitzer received her PhD from Montana State University.
