Originally from Longmont, Colorado, Casey James Miller is a proud graduate of the Li Po Chun United World College of Hong Kong. After earning a B.A. degree in philosophy, politics, and economics from the University of Oxford (Magdalen College), he completed an M.A. in Regional Studies—East Asia from Harvard University and received his Ph.D. in anthropology from Brandeis University. Before coming to Muhlenberg, Miller was a visiting assistant professor of anthropology in the Department of Anthropology at Bryn Mawr College and a postdoctoral research fellow at the Population Studies & Training Center at Brown University.

Outside of academia, Miller is an avid gardener and also stays busy fixing up the former Quaker meeting house built in 1890 in Horsham, Pennsylvania where he lives with his husband and is constantly doing battle with the local deer, groundhog, and squirrel populations. Miller is also a member of the board of directors of the Mid-Atlantic Carnivorous Plant Society.
