Dr. Todd Humphreys’ expertise in assessing spoofing threats has catalyzed modern research in location and timing security. His lab has conducted demonstrations of navigation and timing deception of autonomous systems. In fall 2011, at the invitation of a U.S. Dept. of Energy lab, his group showed that the time synchronization of a phasor measurement unit, a critical element of the smart grid, could be arbitrarily manipulated by GPS spoofing. Months later, by invitation of the U.S. Dept. of Homeland Security, his lab conducted a live-signal spoofing attack in which a target UAV helicopter became remotely controllable as if caught in a tractor beam. In June 2013, his group demonstrated the potency of GPS spoofing in targeting the navigation system of an $80M super-yacht by driving the yacht several kilometers off course without triggering alarms. The UAV demonstration led to Humphreys’ first invitation to testify before a congressional committee.

Dr. Humphreys has made significant contributions to the area of robust perception. This work seeks to ensure reliable autonomous system navigation, collision avoidance, and timing despite harsh sensing environments for precise vision-based sensing and massive signal-of-opportunity exploitation. His group has made contributions to precise position estimation for consumer mobile applications and to remote sensing instrumentation.

Dr. Humphreys is an assistant professor in the Department of Aerospace Engineering and Engineering Mechanics at The University of Texas at Austin, where he is the director of the University of Texas Radionavigation Laboratory. He received his PhD in Aerospace Engineering from Cornell University. He has been an invited keynote speaker in many technical conferences. His TED talk on location security and privacy has over 600,000 views; and he has spoken to millions on security and privacy-related topics through mass media outlets.
