His recent scholarly activity includes contributions to several edited volumes, one on political religion theory published in Germany through Wallstein Verlag, and another on racial and religious antisemitism published through Indiana University Press. He has also contributed the chapter on Religion and the Churches to the benchmark Oxford Short History of Germany: The Third Reich, and the chapter on Germany to the Clerical Fascism volume through Routledge. He has presented his research at several academic venues in North America and Europe, including Indiana University, Ohio State University, the University of Wisconsin-Madison, the University of Texas-Austin, King's College at the University of London, the Max Planck Institut in Goettingen, and at the Modern European Research Seminar in the Faculty of History at Cambridge University. He was also featured in a documentary on Hitler's religious views that aired on The History Channel in 2009.

His current research interests include the ideological origins of American Fascism, and conceptions of mutability and identity in the Third Reich. The ways in which Nazis attempted to gauge the racial affiliation of those who, in the Nazi imagination, were neither German nor Jewish, has long been a question of debate. How the Nazis determined racial identity for so-called half-castes of mixed European and non-European ancestry, and the ways in which the Nazis acknowledged that cultural categories guided their racial thinking, are among the questions his current research interests seek to answer. In support of his research he has earned grants and awards from the Social Science and Humanities Research Council of Canada, the Max-Planck Institut fuer Geschichte in Germany, the Sassoon International Center for the Study of Antisemitism in Israel, the Faculty of History at Oxford Brookes University in the United Kingdom, and the United States Holocaust Memorial Museum, as well as from the Office of Research and Graduate Study at Kent State University.

At universities in the United States and Canada, he has taught a variety of courses relating to different aspects of modern European and Jewish history, including lecture courses on Germany since 1870, Modern Europe, 1890-1945, and The Holocaust, as well as undergraduate and graduate colloquia on topics such as Historiography, Comparative Fascism, and Religion and Society in the Modern West. He won the Distinguished Teaching Award from the College of Arts and Sciences at Kent State in 2004, and has been nominated an additional three times. He also supervises PhD and MA students in topics relating to Nazi Germany and the Holocaust.
