Current research projects include:
Congressional Foreign Policy Entrepreneurship: This research explores the power of junior congressional entrepreneurs to influence U.S. foreign policy. The project employs a mixed-methods approach, including structured, focused case studies of innovation and obstruction in contemporary U.S. foreign policy debates. Results of this study were published in a recent book with the University of Michigan Press, as well as planned academic journal articles over the next three years.
Critical Norm Theory and Nonproliferation: This research program critically examines constructivist security studies theory regarding the power of international norms to regulate state behavior. I have developed research projects on critical norm theory and nuclear nonproliferation with Dr. Carmen Wunderlich and colleagues at the Peace Research Institute in Frankfurt/Leibniz Institut Hessische Stiftung Friedens und Konfliktforschung (PRIF/HSFK) and the Peace Research Center Prague at Charles University.
Strategic Culture in the 21st Century: This research analyzes the role of strategic culture in shaping national security policy. This research program includes an examination of strategic culture and tailored deterrence, as well as a study of links between strategic culture, weapons of mass destruction policy, and threat assessment.
U.S. Political Polarization, Factionalism, and Foreign Policy: This research program explores the impact and influence of ideological factions such as the House Freedom Caucus and the Progressives on various aspects of the U.S. foreign policy-making process. I have presented conference papers and have articles in development that examine how the rise of a new generation in Congress and active factions have impacted key areas of U.S. foreign policy-making. In collaboration with Dr. Patrick Homan, we are advancing a new book, conference papers, and articles on factionalism on foreign policy.
