William J. Horrey, Ph.D.

Liberty Mutual Research Institute Research Scientist William J. Horrey, Ph.D. Dr. Horrey joined the Research Institute in 2005 as a research scientist in the area of transportation safety.  His investigations focus on driver behavior and distractions from in-vehicle devices, including cell phones and visual displays.  Specifically, his interests involve modeling driver’s visual attention while interacting with these devices, and determining the associated performance decrements.  His research also examines how driver risk perceptions differ from actual hazards.

Previously, Dr. Horrey was a graduate research assistant with the Beckman Institute for Advanced Science and Technology at the University of Illinois (Urbana-Champaign).  In this position, he conducted simulator research on various aspects of driver behavior and safety.  His work also involved the design, development, and application of a variety of human factors research projects.  At the University, he also taught laboratory classes in human factors and engineering psychology. 

Dr. Horrey earned his Ph.D. and M.A. in psychology from the University of Illinois and his B.Sc. in psychology with honors from University of Calgary, (Alberta, Canada).  An active member of  the Human Factors and Ergonomics Society, he chairs the Surface Transportation Technical Group, serves on the Society’s Publications Committee, and is an Associate Editor for the organization’s peer-reviewed journal Human Factors. He is also a member of the Transportation Research Board, the American Psychological Association, and the Association for Psychological Science.
