Dr. Khan’s work has spanned hundreds of complex cases and has involved detailed analysis of compliance with standards and regulations (including OSHA, MSHA, NHTSA, FMVSS, CPSC, FRA, FDA, and others), user behavior, warnings and instructions, training effectiveness, job design, and workplace safety programs. She has designed and evaluated warning labels, safety instructions, operator manuals, and as well as safety program documentation for major manufacturers and organizations. She has evaluated injury risks from operations (such as machine guarding, lockout/tagout), conducted comprehensive safety audits, analyzed injury and illness data trends, and developed injury prevention strategies for state-run facilities, including those of the State of Wisconsin and the University of Wisconsin, as well as for major private-sector corporations.

Dr. Khan’s work has included evaluating and researching human factors issues related to occupant restraint systems, seatbelt reminder systems, seatbelt use/non-use, seating and occupant positioning, in-vehicle warnings and information in owner’s manual, driver decision-making and performance, driver-assistance technologies, perception-reaction time, visibility, distraction, and fatigue. Her work has involved the application of human factors principles to issues governed by Federal Motor Vehicle Safety Standards (FMVSS), National Highway Traffic Safety Administration (NHTSA) regulations and guidance, applicable standards, New Car Assessment Program (NCAP) requirements and evaluation protocols, and industry practices. She has evaluated accidents involving passenger vehicles, commercial vehicles, rail transportation systems, and industrial equipment regarding the interaction between people and complex systems.

Dr. Khan advises leading manufacturers on product development and safety strategy. She has conducted usability testing, use/misuse/abuse testing, warning label comprehension studies, human-centered design assessments, and pre- and post-market evaluations to determine compliance with global standards (such as ANSI, ISO, ASTM, SAE, etc.) and to understand user perceptions and behavior across a wide range of products and industries. Her consulting work has supported clients in developing and improving product design, instructions, and manuals, as well as assisting in product recalls and broader risk-management initiatives. She has also assessed corporate safety climate to reduce injury risk from unsafe work practices and behaviors.

Dr. Khan has specialized expertise in evaluating incidents that involve human response to alarms and sounds, and uses advanced tools such as a binaural head measurement system to reconstruct the sound environment in accident scenarios and opine on the audibility of alarms or other auditory warnings. She has conducted occupational noise exposure assessments using dosimetry and sound level monitoring equipment and has evaluated issues involving OSHA noise regulations, workplace noise exposure, and occupational noise-induced hearing loss. Her analytical capabilities are complemented by a practical understanding of engineering design, human performance research, field testing, regulatory frameworks, and industry best practices.

Dr. Khan is an active member of several national and international standards development committees. Her current roles include participation in ANSI Z535.7 (product safety information in electronic media), ISO TC 145 (graphical symbols), ISO TC 127 SC 3 WG 1 (graphical symbols for equipment), ISO TC 127 SC 2 WG 35 (bystander awareness), ASTM E34 (occupational health and safety), and several other committees. She is also a member of the Association of Equipment Manufacturers (AEM), where she contributes to continuing education programs on safety and human factors for equipment manufacturers.
