Dr. Todd Humphreys is an Assistant Professor in the Department of Aerospace Engineering and Engineering Mechanics at The University of Texas at Austin, and Director of the Radionavigation Laboratory at UT-Austin, which specializes in developing theory and technologies for secure, robust, and precise perception, especially as related to autonomous vehicles. Dr. Humphreys’s research has directly influenced broad public policy related to autonomous vehicles. He has twice testified before the U.S. Congress on safety and privacy in an age of drones, has contributed to two Government Accountability Office reports, was a special consultant for the National Risk Assessment of GPS Vulnerability, and directly contributed to Texas House Bill 912, which protects privacy by setting limits on public and private use of drones. Moreover, three significant government programs were initiated in large part due to his research, the FAA Alternative Position, Navigation, and Timing (APNT) program.
