Dr. Scully is a cognitive psychologist with over 15 years of experience. She has expertise in human performance, vehicle operator behavior, auditory and visual perception, attention and distraction, stress and fatigue, human memory and experience, and information processing. Dr. Scully applies this expertise to the investigation of human factors in transportation accidents, slips, trips, and falls, compliance with safety information and warnings, and the use of in-vehicle technologies such as Advanced Driver Assistance Systems (ADAS).

Prior to joining Exponent, Dr. Scully's graduate work focused on understanding the various factors that can affect memory and recall, including examining how memory modification techniques can be used to update attitudes toward others. Additionally, Dr. Scully has also examined the impact of collaborative remembering and the strength of memory reactivation on long term memory change. Dr. Scully has expertise in several statistical and research methodologies including quantitative data analysis, meta-analysis, and electrodermal activity (EDA) data collection and analysis.
