I am a historian, writer and academic, specializing in modern European history, particularly the history of memory, violence, radicalism, and political extremism.

Since 2010, I have been Professor of Modern History at University College Dublin and Director of the Centre for War Studies.

I am the author of several critically acclaimed and award-winning books, including The Vanquished: Why the First World War Failed to End (2016), Hitler’s Hangman: The Life of Heydrich (2011), and The Bismarck Myth: Weimar Germany and the Legacy of the Iron Chancellor (2005). My most recent monograph is November 1918: The German Revolution (2020).

As an academic, I have taught undergraduate and graduate courses covering nineteenth and twentieth-century European and German history at Oxford, Sciences Po Paris, and University College Dublin. I am also the co-director (with Sönke Neitzel) of the MA in International War Studies, a two year Dual Degree programme in which students spend one year in Potsdam and a second year in Dublin.
