Colleen McDonough received her B.S. in zoology from University of Wisconsin at Madison. She started studying nine-banded armadillos (Dasypus novemcinctus) while at the University of California at Davis, where she received her Ph.D. in Animal Behavior in 1992. At present, she is a professor in the Biology Department at Valdosta State University in Georgia, USA where she works with her husband, Jim Loughry. Over the last 20 years, their research has focused on effects of polyembryony on ecology and behavior of nine-banded armadillos. They mostly work with D. novemcinctus in the United States, but conducted research in Brazil for a short time. Currently, they are investigating the consequences of leprosy on a population in western Mississippi.
