Sue Howell is Primatologist and Biological Anthropologist who joined the Department of Anthropology at UCCS in 2019.  Her training includes BA degrees in Studio Art and Physical Anthropology as well as MS and Ph.D. degrees from Arizona State University, School of Evolution and Social Change in Biological Anthropology.  Her dissertation research focused on the behavioral development of Pan troglodytes (chimpanzees).  Her post doctorial research focused on the behavioral biology of free-ranging rhesus (Macaca mulatta). She has studied a variety of macaques including Macaca mulatta from India and Macaca fascicularis from Southeast Asia. Her current research focuses on social systems ecology and conservation of Alouatta paliata paliata (howler monkeys) at La Selva Biological Station in Costa Rica.  In addition to primatology, she has a broad interest in several areas of anthropology including anthropological theory, forensics/osteology/comparative osteology as well as the culture of animal welfare and serves as a primate behavioral consultant and Chair for an animal care and use committee (IACUC).  In her spare time, she enjoys art museums, acrylic painting, scientific illustration, and fictional writing.
