Dr. Joshua Tallis is a research scientist and political-military analyst at the Center for Naval Analyses, the US Navy’s federally funded research and development center. Specializing in Arctic policy, maritime security, and US naval strategy, he has advised Navy leaders at tactical, operational, and strategic levels of command. Tallis most recently served as the analytic advisor for the commander of US Sixth Fleet (Naval Forces Europe and Africa), where his primary roles were leading special research projects and incorporating empirical analyses into command deliberations. Previously, Tallis served as the embedded analytic advisor to the commander of Carrier Strike Group Eight onboard USS Harry S. Truman. In that position, he analyzed the Navy’s first aircraft carrier deployment north of the Arctic Circle since 1991, becoming the first US naval analyst to directly study High North carrier operations since the Cold War. When not embedded with the fleet, Tallis serves as a CNA project director, in which role he has led several congressionally mandated studies on the Arctic and maritime security for sponsors across the Department of Defense and the Intelligence Community. Tallis has won several corporate awards for his research and leadership, including CNA’s highest distinction for project management. He is the author of the Naval Institute Press book, The War for Muddy Waters: Pirates, Terrorists, Traffickers, and Maritime Insecurity, and most recently authored the chapter on maritime terrorism for the Routledge handbook on maritime security. He holds a Ph.D. in international relations from the University of St Andrews and is an adjunct professor at The George Washington University, where he teaches a course on piracy and irregular maritime threats.
