From contractors fighting international wars, to corporations regulating global markets, to governments collaborating with nongovernmental entities to influence foreign elections, overlapping relations of public and private hybridity abound in the major stories of global sovereign power. I call this phenomenon “hybrid sovereignty” and study its forms and dynamics using cases such as the English East India Company, Blackwater, the International Chamber of Commerce, and Amnesty International.


This project develops original research on the global politics of Big Tech, particularly Google and Facebook, as they engage in unprecedented "algorithmic governance." I lead an undergraduate research group at Purdue on Big Tech and Political Responsibility. Our current project builds an original dataset of Facebook's political harms from 2004 till present and tracks the related global regulatory landscape to identify the most pressing accountability gaps.

Purdue undergraduates in the research group:

     Brooke Price (2019 – )

     Rachel Young (2019 – )

     Kaitlyn Petratos (2020 – )

     Madeleine Yang (2020 – )

     Shannon Kang (2021 – )

     Amanda Shie (2021 – )

     Nathan Miller (2021 – )

     Taewon Kang (2021 – )

     Matthew Heagerty (2019 – 2021)

     Allison Kelly (2019 – 2021)

     Zhuoran Qiu (2020 – 2021)

     Viraj Desetty (2019 – 2020)

     Kayla Murphy (2019 – 2020)

I have an ongoing interest in social theory clarifying relational approaches like constructivism and actor-network analysis (see publications below) and exploring responsibility in global politics.


I am trained in comparative historical, archival, big data, and interpretive methods. I collect primary data from national archives in the United States, England, and France and organizational archives in the Netherlands and France. My research and travel have been generously funded by: The Andrew Mellon Foundation and the American Council of Learned Societies (ACLS); The Buffett Institute for Global Studies, the Department of Political Science, Legal Studies Graduate Program, and Critical Theory Graduate Cluster, all at Northwestern University; as well as the International Studies Association, International Studies Association-Northeast, British International Studies Association, and the Aberystwyth-Lancaster Graduate Colloquium.
