Daniel McGehee has been obsessed with car crashes for over 20 years. He is interested in every aspect of them - from how, when and why they occur, to technologies for avoiding them altogether. His driver performance, distraction, and technology development research has led to innovative, interdisciplinary collaborations involving engineering, medicine, and public health. McGehee's research has helped policy makers to improve government safety standards, as well as state and federal laws. While the first generation of safety systems were designed to help protect occupants in cars, his research deals with preventing or reducing the severity of crashes. Such technologies will ultimately lead to higher levels of automation on our roads.
