Lindsay Long
Lindsay O'Hara Long, Ph.D.
Senior Scientist
Human Factors & Industrial Engineering
  • Bowie, MD

Dr. Long’s research focuses on how humans perceive, move, and interact within their environments, and how the capabilities and limitations of human perception, cognition, and physiology impact their interactions, particularly with respect to safety and safety-related behaviors. She has expertise in the fields of human performance and human factors, including visual and haptic (tactile) perception, attention and distraction, warning compliance, and the mechanics of pedestrian gait and falls. Dr. Long has published scientific research assessing human behavior and human factors issues in areas such as training and skill acquisition, perception and communications, displays and interfaces, unmanned devices, surgical expertise, and minimally invasive surgery, and she has experience applying her scientific expertise to analyses of accidents and injury, safety information, and product use.

Her expertise in understanding how humans perceive and use perceptual information applies to the detection of warnings and hazards, the use of training and safety information, the ability to perceive and navigate walking surfaces, the use of information while driving and operating machinery, and the perception of obstacles and pedestrians under darkness and limited visibility conditions. She has analyzed human factors issues in product liability, medical malpractice, industrial accidents, slips/trips and falls, and transportation cases, among others. She is also a certified XL Tribometrist, allowing her to scientifically evaluate floor surface conditions relating to human slips, trips, and falls. Furthermore, Dr. Long has extensive experience conducting research studies using human subjects under real-world and laboratory contexts, including usability and user- experience research, where she applies findings to the design and development of instructional materials, consumer products, and interface displays.

During her graduate studies at Clemson University, Dr. Long worked for the National Transportation Safety Board, where she was involved with research studies addressing human factors contributors to accidents within the surface and aviation industries. She also worked for an engineering research and development firm, where she was involved in numerous military-related research efforts. Prior to joining Exponent, Dr. Long also worked as a User Experience Researcher for an interactive marketing company, where she studied consumer behavior, product usability, and user interaction in multimedia marketing.
