What kinds of professionals work in human-factors engineering?

Human-factors engineering is a multidisciplinary profession that integrates expertise from various scientific and technical fields to design systems, machines, and environments that account for human capabilities and limitations.1

Rather than being limited to a single job title, the profession comprises a range of scientists and engineers who collaborate to ensure the safety, comfort, and productivity of human users. Because the field draws upon a broad scope of knowledge, professionals in this area include:1

• Engineers: Specialists from various branches of engineering who apply technical design principles to machine systems.1
• Scientists: Experts from the social and physiological sciences, including psychology, anatomy, anthropometry, applied physiology, sociology, and toxicology.1
• Specialists: Professionals focused on industrial design, operations research, and environmental medicine.1

While some specialized groups may use labels such as bioengineering, biodynamics, or bioastronautics, these roles share the same fundamental goal of optimizing the human-machine interface through rigorous scientific methods.12
