Welcome to my website.
I am a historian of twentieth-century Europe, with a particular focus on the period of the two world wars, broadly defined. I hold an MA from Berlin’s Humboldt Universität and a DPhil from Oxford University where I also spent three years as a British Academy Postdoctoral Fellow and a further two years as a Lecturer at the History Faculty and at Balliol College. I am currently Professor of Modern History at University College Dublin and Founding Director of the Centre for War Studies. I am also Principal Investigator of the ERC Advanced Grant project CivilWars.
