Elizabeth A. Nichols, Ph.D.

Senior Scientist

Human Factors

Professional Profile


Dr. Nichols’s work focuses on the cognitive, developmental, perceptual, and physical human factors issues relating to accidents and injuries. Her work includes the evaluation and development of warnings and safety information and analysis of its effectiveness. She is involved in the scientific study of human behavior in response to audible alarms, such as people’s response to smoke alarms. She has investigated human factors that affect one’s ability to escape from fires.

She uses a wide range of large-scale databases and analytical techniques to investigate safety-related behaviors, injuries and accident patterns, such as those associated with recreational and sports activities, health and fitness equipment, other consumer products, and motor vehicles. She provides technical assistance in the review and analysis of consumers’ reports of incidents submitted to government agencies (CPSC, FDA, etc.) and to manufacturers. Dr. Nichols has conducted product usability studies to examine the physical and cognitive abilities of children and adults as they interact with particular products and environments.

Prior to joining Exponent, Dr. Nichols completed a Ph.D. in experimental psychology with a focus in neuroscience at Stanford University and worked as a research associate at SAM Technology and the San Francisco Brain Research Institute. During that time she used a variety of experimental methods, including behavioral, neuroimaging, electrophysiological, and patient case studies, to investigate the brain mechanisms that support memory.
