Dr. Ehsani's research examines the role of policy and technology on driver behavior and safety. He has conducted research on the effectiveness of licensing systems and distracted driving policies on crashes and injuries at a population level. He is currently collaborating on a number of naturalistic driving studies that examine individual-level driver behavior in a variety of contexts (e.g. while teens are learning to drive). In addition, he is conducting research on how autonomous vehicle testing and deployment can be used to advance both safety and equity.
