Dr. Hageman joined the Appalachian faculty in 1998, coming from a Research Associate position at the Field Museum of Natural History, and a postdoctorial appointment at the University of Adelaide, South Australia. His research interests are in patterns and processes of evolution, particularly microevolution and speciation. He also studies the interaction of colonial growth habits and their environments and relationships between phenotypes, genotypes and the environment. His primary study groups are Cenozoic cheilostomate and Paleozoic stenolaemate bryozoans.
Dr. Hageman was awarded the Board of Governors’ Appalachian State University College Teaching Award in 2009, and the William Strickland Outstanding Junior Faculty Award in 2000. He was also named as a distinguished lecturer for the Paleontological Society (2000-2002), and most recently has served as the editor of the Journal of Paleontology. He is a two time Fulbright Research Fellow, 2006 Center for Marine research - Rudjer Boskovic Institute, Croatia, and 2018 at the Institute of Oceanology of the Polish Academy of Sciences in Sopot, Poland and is one of the faculty who have made Appalachian one of the leaders in faculty Fulbright scholars in the UNC System and the first in the country for Fulbright scholars among masters institutions in 2018. Dr. Hageman is also the GES Department's Transfer Student Mentor and received the University College, Transfer Student Champion Award in 2019. In 2019 he was elected as a Fellow in the Geological Society of America.
