Personal Bio

Ian McCulloh holds joint appointments as a Parson’s Fellow in the Bloomberg School of Public health, a Lecturer in the Whiting School of Engineering and as chief scientist in the Cyber Warfare Systems Group of the Applied Physics Lab, at Johns Hopkins University.  His current research is focused on strategic influence in online networks and understanding the cognitive dimension of the information environment.  He is the author of “Social Network Analysis with Applications” (Wiley: 2013), “Networks Over Time” (Oxford: forthcoming) and has published 46 peer-reviewed papers, primarily in the area of social network analysis.  He retired as a Lieutenant Colonel from the US Army after 20 years of service in special operations, counter-improvised explosive device (C-IED) forensics and targeting, and weapons of mass destruction (WMD) defense.  He founded the West Point Network Science Center and created the Army’s Advanced Network Analysis and Targeting (ANAT) program. In his most recent military assignments as a strategist, he led interdisciplinary PhD teams at Special Operations Command Central (SOCCENT) and Central Command (CENTCOM) to conduct social science research in 15 countries across the Middle East and Central Asia to included denied areas, which he used to inform data-driven strategy for countering extremism and irregular warfare, as well as empirically assess the effectiveness of military operations.  He holds a Ph.D. and M.S from Carnegie Mellon University’s School of Computer Science, an M.S. in Industrial Engineering, and M.S. in Applied Statistics from the Florida State University, and a B.S. in Industrial Engineering from the University of Washington.  He is married with four children and a granddaughter.
