I am an Assistant Professor of Computer Science and the Tandy Chair of Cyber Security and Information Assurance in the Tandy School of Computer Science at the University of Tulsa. My research focuses on the economics of information security, the study of electronic crime, and the development of policy for strengthening security. I am also interested in digital currencies and critical infrastructure protection. I direct the Security Economics Lab at TU. I'm also Director of StopBadware, a non-profit anti-malware organization. Prior to joining TU, I was a postdoctoral fellow at the Center for Research on Computation and Society (CRCS) at Harvard University, the Norma Wilentz Hess Visiting Assistant Professor of Computer Science at Wellesley College, and an assistant professor at Southern Methodist University. I completed my PhD at the University of Cambridge as a Marshall Scholar, supervised by Prof. Ross Anderson.
