Naomi Dunn is a senior research associate in the Division of Vehicle, Driver, & System Safety. She joined VTTI from the University of New South Wales in Sydney, Australia, where she received her Ph.D. in human factors in 2011. Over the past 18 years, Dr. Dunn has completed human factors- and transportation safety-related research projects in a variety of domains, including advanced driver assistance systems, automated vehicles, impaired driving, commuter and freight rail safety, crash causation, and driver behavior and performance. Recent efforts have been aimed at better understanding the impact of driving automation systems on driver-vehicle interactions and the potential unintended consequences associated with their use. She has led projects focused on drug- and alcohol-impaired driving, including the safety implications of marijuana legalization and the development of a sentinel surveillance system for drug use by drivers involved in crashes. Additionally, Dr. Dunn has ongoing projects sponsored by the Federal Railroad Administration where she is investigating various elements of rail safety as related to states of reduced alertness, such as fatigue and inattention.
