I am a historian of right-wing extremism, de-radicalization, and democracy and an associate professor of European history at Rowan University.

My award-winning book, Everyday Denazification in Postwar Germany: The Fragebogen and Political Screening During the Allied Occupation, appeared with Cambridge University Press in 2023. It explores Allied army efforts to simultaneously punish and reorient former Nazis and the consequences of denazification for ordinary Germans. (Learn more about my book by listening to this New Books Network interview or reading this Fifteen Eighty Four Blogpost.) In recent years, I have also written research articles on post-WWII trauma recovery, memory construction and the whitewashing of Nazi pasts, Holocaust education and virtual reality, and eugenics legislation.

I am currently involved in a number of projects related to combating violent extremism in Europe and the United States, including a global history of anti-fascism campaigns in postwar Germany, Austria, Italy, and Japan (read more here). I have also begun work on The Global Deradicalization Database (GDD), which is a digital inventory of historical undertakings to reduce, eliminate, and prevent violent political extremism. This catalogue will better inform how societies, especially those in the United States, identify and interpret violent extremism and how community groups, governments, and law enforcement agencies uphold democratic principles and practices. For a sampling of my public-facing work, you can read pieces on the American fight against far-right domestic terrorism and Putin’s purge of Ukrainian culture.

My scholarship has been awarded grants and fellowships from an array of sources, including the German Research Foundation, German Historical Institute, German Academic Exchange Service, French National Research Agency, Botstiber Institute for Austrian-American Studies, and Social Sciences and Humanities Research Council of Canada. I am a Distinguished Guggenheim Scholar and a Humboldt Fellow.

I am an Associate Professor of Modern European History at Rowan University and I also serve as Director of Research for the Rowan Center for the Study of the Holocaust, Genocide, and Human Rights. I have taught more than forty undergraduate and graduate courses on topics such as global Europe, the West in the World, World War II, Nazi Germany and the Holocaust, radicalism and dictatorships, comparative fascism, and historical methods.
