Larry Lewis, Ph.D.
Director, Center for Autonomy and AI
Larry Lewis is the Director of the Center for Autonomy and Artificial Intelligence at CNA. His areas of expertise include lethal autonomy, reducing civilian casualties, identifying lessons from current operations, security assistance, and counterterrorism.
Lewis spent a decade analyzing real world operations as the project lead and primary author for many of DOD's Joint Lessons Learned studies. For example, he was the lead analyst and co-author (with Dr. Sarah Sewall) for the Joint Civilian Casualty Study (JCCS) in support of GEN Petraeus, GEN McChrystal, and ADM Olson (SOCOM); GEN Petraeus described the study as "the first comprehensive assessment of the problem of civilian protection." His other areas of expertise include counterinsurgency and high value targeting in Iraq, Afghanistan, the Philippines, Colombia, and elsewhere. In addition, he authored the 2012 "Lessons from a Decade of War" report for CJCS. He also served as senior advisor to the Department of State's Assistant Secretary for Democracy, Human Rights, and Labor, and was on the U.S. delegation to the CCW regarding Lethal Autonomous Weapon Systems (LAWS).
Lewis has a Ph.D. in Physical Chemistry from Rice University.

Larry Lewis says, “There are two main mechanisms for civilian causalities. One is indeed collateral damage. There is a military engagement of what they consider to be a valid target, and then there are civilians who are inadvertently in the area. The other is misidentification, so a military force believes that the target is valid, however, it makes a mistake and inadvertently targets civilians.”
