Program Director and Instructional Professor
Research Summary

Dr. Sheets was trained as a Physicist, but has worked for many years as an applied Data Scientist, working in a wide variety of collaborative, interdisciplinary teams to address a variety of questions. He has published scientific works in biology, entomology, forensics, paleobiology, physics, anthropology and art conservation. He is a co-author of a leading textbook in Geometric Morphometrics,  a set of methods for carrying out hypothesis testing based on the shapes of non-human organisms. His current work focuses on approaches to measuring the performance characteristics of forensic firearms and handwriting examiners, and on data science approaches to the analysis of surface textures on art objects.
