At George Mason I have the phenomenal good fortune
to work with some of the best young minds in the business.

My research explores the interaction of epistemology, politics, and the media.  With a nod to a former defense secretary, I am interested in how news coverage influences what we know about what we know.  My research is driven by large-n content analyses of TV and digital platforms, assessing how certitude is expressed and transmitted through the public sphere.  More information about my research and teaching can be found on my website.

Matt Fay

political science

I am a PhD candidate in the political science program at George Mason University’s Schar School of Policy and Government concentrating in international security. My research interests include military change, conventional deterrence, civil-military relations, and defense politics. My dissertation research focuses on how military organizations adapt in conventional war.

I live in Pittsburgh, but I was born and raised on the south side of Chicago. My bachelor’s degree is in political science, with a minor in history, from St. Xavier University in Chicago. I have a master’s in international relations from American Military University and a master’s in history from Temple University. I previously served as a defense policy analyst and director of defense and foreign policy studies at the Niskanen Center. I periodically appear on the Secure Line podcast to discuss U.S. foreign policy and national security. When not working, I enjoy reading, movies, running, and cooking. I remain stupidly optimistic that next year will be the year the Chicago Bears finally win another Super Bowl
