Jeremy D. Schwark, Ph.D.
Senior Scientist

Dr. Schwark has expertise in visual and auditory perception, visual search, attention, memory, cognition, emotion, and human-computer interaction. He uses this expertise to analyze human performance and identify causes of perceptual and cognitive errors. Dr. Schwark also investigates the capacity of attention and working memory and the errors that occur as workload increases. He has extensive experience evaluating human performance in both laboratory and field settings and has employed a number of physiological measures such as reaction time, eye-tracking, and electromyography.

Dr. Schwark also has expertise in the interaction between humans and machines. His work has explored the relationship between humans and automated systems and identified several causes of errors due to people under- or over-relying on these systems. His experience in this area involves work with unmanned aircraft, where he conducted field studies funded by NASA, the FAA, the DoD, and the United States Air Force. His work in visual search incorporates the use of computer-aided diagnostics and focuses on improving the architecture of these automated aids in order to improve the performance of radiologists. He also has experience evaluating the usability of interface designs and the impact of emotion on computer use and user behavior.

Dr. Schwark received his Ph.D. in Engineering Psychology from New Mexico State University in 2014. His graduate research focused on improving the detection of rare targets and advancing models of human vision, attention, and memory. Dr. Schwark’s graduate work was supported by fellowships from the Howard Hughes Medical Institute and the National Science Foundation. Prior to joining Exponent, Dr. Schwark interned at the Naval Surface Warfare Center as a Human Systems Engineer, where he examined the impact of noise-induced hearing loss on warfighter performance.
