Faculty & Staff

Roman Miller
Professor of Biology
Dr. Roman J. Miller is the Daniel B. Suter Endowed Professor of Biology at Eastern Mennonite University, Harrisonburg, VA where he has taught courses in physiology, anatomy, developmental biology, animal science, bioethics, and philosophy of science for the past twenty-two years. Roman received his PhD in biomedical science (physiology major with minors in cell biology and reproductive biology) from Kent State University, Kent, Ohio and completed a post-doctoral research program at West Virginia University, Morgantown, WV, prior to teaching at EMU. His research interests at EMU include the development and function of male accessory sex glands in rodents, creating conditions for sustainable organic blueberries, and the role of an Anabaptist perspective in bioethics and issues of science.

Kim Gingerich Brenneman
Professor of Psychology
Dr. Kim Gingerich Brenneman, graduate of the EMC class of 1983, began her teaching career at Eastern Mennonite College in the fall of 1989. She received her Ph.D. in the spring of 2001 in Developmental and Educational Psychology. Her dissertation was titled The Well-being of Internationally Mobile Adolescents. She continues her interest in the well-being of Third Culture Kids.

Stephen Cessna
Associate Professor of Biology
Dr. Steve Cessna received his BA in chemistry and biochemistry in Colorado and then taught middle school math and science in Lesotho in southern Africa, with the Mennonite Central Committee, a relief and development organization of the Mennonite Churches. After returning to the U.S., getting married and moving to Indiana, Steve earned a PhD in biochemistry and molecular biology. His graduate research included genetically altering tobacco plants so that they express a gene from a bioluminescent jellyfish. Cellular calcium concentrations could then be easily measured in these ‘glow-in-the-dark’ plants. At EMU, Steve has continued this research, involving EMU students in the study of plant stress, with applications in sustainable agriculture and invasive species ecology. Steve teaches biochemistry, chemistry, and botany courses.

Jeffrey Copeland
Assistant Professor of Biology
Dr. Jeffrey Copeland has been at EMU for the past 3 years and has taught courses in genetics, cell biology, microbiology, nutrition, and immunology. Prior to coming to EMU, Jeff lived in Los Angeles where he earned his Ph.D. in biology from the California Institute of Technology and completed his post-doctoral training at the University of California, Los Angeles. His current research interests are an expansion from his post-doctoral work, using the fruit fly Drosophila melanogaster as a tool to understand the genes important for the aging process.

Julia Halterman
Assistant Professor of Biomedicine
Dr. Julia Halterman is an assistant professor of biomedicine at EMU and is teaching undergraduate Human Anatomy & Physiology, Animal Form & Function, and Nutrition Fundamentals. She also serves as faculty for the MA in Biomedicine graduate program at EMU. Julia received her BS in Biology at Texas A&M University and her PhD in Pharmacology at the University of Virginia. While completing a postdoctoral fellowship at the University of Virginia, Julia taught as an adjunct assistant professor at Piedmont Virginia Community College.

Greta Ann Herin
Professor of Biology (Sabbatical)
Dr. Greta Ann Herin is currently teaching Mammalian Anatomy, Human Anatomy and Physiology I and II, Neuropsychology and Advanced Neurobiology. She has also taught: Mammalian Physiology, Biological Explorations, Molecules, Genes, and Cells, Senior Seminar “Origins” and co-taught Concepts in Biology, and a Colloquium called “Passion and Obsession”. Greta Ann serves as a Pre-professional Health Sciences advisor. She has dual Bachelors Degrees in Biochemistry and Psychology from Kansas State University and a PhD in Neurobiology from the University of Pittsburgh School of Medicine. Her dissertation was on interactions among modulators of NMDA receptors, an important glutamate receptor in the brain. In addition Greta Ann did a post-doctoral fellowship at the Max-Planck Institute for Brain Research in Frankfurt, Germany. There she studied metabotropic glutamate receptors. Greta Ann is on sabbatical during the 2013-14 academic year.

Ann Hershberger
Professor of Nursing
Dr. Ann Hershberger, professor of nursing and former director of the MS in nursing and leadership program, has worked in family health, community health, international health, and nursing education since 1976. Ann and her husband Jim, a pastor, spent more than a decade in church-sponsored service in Central America. She earned her PhD from UVA and spent a year in Nicaragua researching her dissertation on “Nicaraguan non-governmental health organizations, communities served, donor agencies, and the Ministry of Health.” On a recent sabbatical she researched the experiences of families in Guatemala and West Bank, Palestine who have hosted EMU cross-cultural students over the last decade. She has been a consultant for Nicaraguan nursing schools, and has been on the board of MCC (Mennonite Central Committee) since 1997.

Carolyn Stauffer
Assistant Professor of Applied Social Sciences
Carolyn Stauffer has taught at the graduate and undergraduate levels at two higher education institutions on the African continent and holds a doctorate in sociology from the University of the Witwatersrand in South Africa. She has lived and worked in Africa (16 years), the Middle East (17 years) and has also been engaged in various shorter-term assignments in North America, Europe and the Caribbean. As a veteran in cross-cultural settings, Stauffer is an agile educator whose pedagogy exemplifies the integration of both left and right brain educational approaches that pervade in our postmodern and global world.

Mark Thiessen Nation
Professor of Theology
For Dr. Mark Thiessen Nation, it was through reading “The Politics of Jesus” by John Howard Yoder that he began to find a theological home in the Anabaptist/ Mennonite tradition. Mark’s subsequent studies with Yoder, doctoral studies under Jim McClendon and Nancey Murphy, and a co-editing friendship with Stanley Hauerwas deepened his commitment to the ministries of peace and justice. Mark earned his PhD from Fuller Theological Seminary. Earlier he earned an MA from Associated Mennonite Biblical Seminaries and an MDiv from Christian Theological Seminary. Acknowledged as one of the foremost authorities in the world on John Howard Yoder, Mark’s passion is to discern with others what it looks like to embody “the politics of Jesus” for our time.

Cheryl Doss
Administrative Coordinator
Cheryl Doss is office coordinator for the Science Center and all the EMU departments lodged there: psychology, biology, chemistry, history and mathematical sciences. She is also the administrative coordinator for the MA in biomedicine program.
