Read MorePhillip Jasper is a Principal on the Human Factors and User Research team at J.S. Held, where he brings nearly 15 years of experience in attention, information processing, human performance, and behavioral science to both litigation support and product development. In his expert witness practice, he provides testimony in cases involving premises liability (e.g., slips, trips, and falls) and motor vehicle incidents. He supports both plaintiff and defense clients with scientifically backed analysis of how people perceive, process, and act on information in real-world contexts. His applied research approach helps uncover the behavioral factors at play in everyday environments as well as high-stakes situations.
Philip's product development work includes evaluating health and safety, user testing, and substantiating marketing claims for a wide range of products, including wearable technologies, augmented and virtual reality systems, personal grooming devices, and cosmetic products.
Philip has deep methodological expertise in usability, eye tracking, and psychophysiological measurement, which he leverages to assess user interaction, attention, and cognitive load. His user research combines academic rigor with practical application, allowing him to translate complex psychological principles into actionable insights for product teams, legal stakeholders, and regulators.
Philip received a Ph.D. in Human Factors Psychology and an M.S. in Applied Psychology from Clemson University. During his graduate work, he conducted research using psychophysiological recordings and eye tracking to assess workload and attention among unmanned aerial vehicle operators, providing insights to inform the design of command-and-control stations and optimize team role organization. Additionally, he evaluated how a wearable device tracked what people ate and how different cues in the environment affected behavior.
Philip is part of J.S. Held’s state-of-the-art User Research Laboratories (URL), where he collaborates with interdisciplinary teams to generate evidence-based insights across the product lifecycle. His work is informed by both proactive human factors work and reactive failure analysis, enabling a comprehensive understanding of risk, usability, and consumer behavior.
