About Dr. Williams
Dr. Williams is an Associate Professor in the Department of Veterinary Sciences at the University of Texas, MD Anderson Cancer Center. He has worked with non-human primates for over 38 years, squirrel monkeys for 35 and owl monkeys for 26. He has worked with the NIH-funded Squirrel Monkey Breeding and Research Resource for 35 years as leader for Resource Management and Behavioral cores. As a comparative psychologist, he has published on social and developmental behavior in captive non-human primates, as well as observational techniques and data analysis. His work over the years has involved the area of biomedical models, specifically developing behavioral scoring methods for studies using MPTP (a Parkinson’s disease model), Creutzfeldt-Jakob disease (both variant and sporadic versions), and Alzheimer’s Disease. More recently, his work has involved studies of the Zika virus in Neotropical primates at the Keeling Center and a proposed project that will deal with the behavioral studies of Zika virus infected animals; in particular social, cognitive, and motor development in infants born to infected dams.
Research Interests
My research efforts are currently divided between managing the research component of the Squirrel Monkey Breeding and Research Resource (SMBRR), and my personal research. The SMBRR is the only NIH funded breeding colony for squirrel monkeys. We manage approximately 500 squirrel monkeys with a focus providing animals, biologics, and expertise on Neotropical primates to the research community. Over the years my efforts have been devoted to the Behavioral Management of the colony, coving both managing group structures and reproduction to maximize the colony production, as well as the environmental enrichment of animals. We are continually evaluating the genetic makeup of the breeding groups in order to optimize the population heterozygosity and maintaining the maximum representation of founder’s genetic composition. In addition, we manage group structure to reduce the amount of agonistic interactions between animals and to promote species-typical behavior in the squirrel monkeys.
My personal research efforts this past year have continued to be focused on three main areas. We continue to collect developmental data on nursery and dam reared infants to compare growth and personality differences. This includes collecting data on neuromuscular and sensor develop in all new infants. We have begun long term studies on socialization in the nursery reared animals as adults in a social group. I have collaborative research project with Dr. Sarah Brosnan to look at cognitive and social learning paradigms in squirrel monkeys. Dr. Brosnan from Georgia State University will look at social economics and the cognitive abilities of the squirrel monkeys. Finally, working with Dr. Kuehl and Scott & White Hospital, we setup the Assisted Reproductive Technology (ART) laboratory. This effort studies behavior and reproductive hormones in the squirrel monkey with the aim of developing techniques that allow for easy ova-retrieval and in-vitro fertilization.
