Jay Todd

Senior Consultant / Ph.D. / Los Angeles/Woodland Hills


Dr. Todd holds a Ph.D. in Psychology with an emphasis in Neuroscience from Vanderbilt University. His Ph.D. research investigated how our brain keeps track of information stored in memory for short periods of time. He also investigated how our memory of an event can impair our ability to become aware of new, unexpected events occurring directly in front of us. As a postdoctoral scholar at the University of Chicago, Dr. Todd investigated the adverse effect of performance anxiety on the ability to perform otherwise simple tasks.

 More recently, Dr. Todd has investigated and published research related to driver and pedestrian visibility and performance. This includes a scientifically based methodology to present the jury with a photograph that accurately portrays the lighting conditions at an accident scene. He has published research on the contribution of different sources of nighttime ambient illumination, which is used to identify the amount of lighting that an individual may use to perceive hazards and other objects in dark environments. He has developed a mathematical model that can be used to accurately and efficiently predict a driver’s available sightline. Collectively, these techniques can help present to the jury a more robust view of the capabilities and opportunities afforded to drivers and pedestrians in a traffic accident. Dr. Todd investigates the effects of limitations in task performance and perception on our awareness and experience of events in our environment. Dr. Todd applies his knowledge and expertise to investigate a variety of incidents involving pedestrians and vehicle operators. Vehicle incidents include passenger vehicles, commercial vehicles (tractor-trailers, box trucks, etc.), bicycles, motorcycles, etc. He investigates misstep /trip-and-falls, retail accidents, diving accidents, perception and response behavior of pedestrians and drivers, issues of lighting and visibility, and use of consumer and industrial products. The scope of these investigations includes analyses of visual and auditory perception, decision-making processes, eye gaze behavior, the contribution of experience and expectancy to awareness and task performance, eye-witness memory, the relationship of age and performance, fatigue, effects of alcohol and drugs on performance, the interaction of hypervigilance and emotions and performance, instructions and safety information, warning application and compliance, and the development of awareness of events and pain perception.
