Welcome to My Little Lab website

I am an Associate Professor at George Mason University in the College of Science within the Department of Computational and Data Sciences (but collaborate with colleagues across the university). I teach data science and computational social science (CSS) courses at the undergraduate and graduate levels. For over a dozen years, I have been leading CSS modeling projects and recently completed a project characterizing the reaction of the population of New York city to a nuclear weapon detonation. I came to Mason after completing successful careers in federal civil service and military service and earned a PhD late in life. My research area is modeling our cognitive processes and behavior using cognitive models and agent-based models of small groups to societies. My office is the Center for Social Complexity where I am a co-Director.
