How do I get to NADS?

Timothy Brown


Dr. Timothy Brown has been working in the driving research field since 1994 and has extensive experience in the design, development, conduct and analysis of driving research studies. His academic and research career has focused on in-vehicle systems, warning systems, medical considerations in driving, and modeling driver performance. Recent work has focused on evaluating vehicle systems to better understand potential safety benefits. He has served as an investigator or as principal investigator on a series of large scale simulator projects and has overseen the recruitment of thousands of participants. He is the author of dozens of journal articles, conference papers, and technical reports, and a recipient of the Jerome H. Ely Award for the best article published in Volume 44 of Human Factors for 2002. Dr. Brown is a member of the National Academies Transportation Research Board User Information Systems Committee, chair of the Joint Subcommittee on the Human Factors of In-Vehicle Systems, and chaired of the human factors workshop planning committee for the 2015 Annual meeting. Additionally, Dr. Brown is a member of the Association for the Advancement of Automotive Medicine. Dr. Brown is also a member of the University of Iowa’s Behavioral/Social Sciences Institutional Review Board.
