Dr. Christopher B. Mayhorn, Psychology Department Head and Professor in the Human Factors and Ergonomics Psychology program, joined the faculty at North Carolina State University in 2002. He earned a B.A. from The Citadel (1992), an M.S. (1995), a Graduate Certificate in Gerontology (1995), and a Ph.D. (1999) from theUniversityofGeorgia. He also completed a Postdoctoral Fellowship at the Georgia Institute of Technology. Dr. Mayhorn’s current research interests include everyday memory, decision-making, human-computer interaction, safety and risk communication for older adult populations. Dr. Mayhorn has more than 50 peer-reviewed publications to his credit and his research has been funded by government agencies such as the National Science Foundation and the National Security Agency. Currently, Chris is serving on the Human Factors and Ergonomics Society (HFES) Government Relations Committee and as the Chair of the Technical Program Committee of HFES. His nonprofessional interests include history, travel, and spending time with his wife, Susan, their son, Colin, their daughter, Sydney, and their keeshonden.
