Christina P. Walker

Welcome! I am a Ph.D. Candidate in the Department of Political Science at Purdue University and affiliated with the Governance and Responsible AI Lab (GRAIL) and the Computational Social Science Lab.

I specialize in comparative politics and methodology, with a research agenda focused on how digital technologies and artificial intelligence (AI) shape political information, public trust, and democratic accountability. I examine both how these technologies affect political behavior and develop new computational and experimental methods to study these effects. On the substantive side, I examine elite strategic communication and information in digital environments, and how citizens process and respond to political content online. On the methodological side, I develop computational and experimental tools that advance how political scientists study behavior in the digital era.

My research has been published in journals such as Political Science Research and Methods, The Communication Review, PS: Political Science & Politics, The AAAI Conference Proceedings, and Politics and the Life Sciences.

I received an M.A. at Purdue University in 2023 and a B.A. in International Relations and French Language & Literature at Oakland University. Previously, I worked in the Michigan State Senate and with USAID and the State Department.
