I am a transnational and global historian of modern Europe and the world. I am currently finishing my Habilitation tentatively titled Water and Stone: The Port of Hamburg in the Age of Global Empires. I started my work on this subject as PI of the project Imperial Gateway: Hamburg, the German Empire, and the Making of a Global Port, funded by the German Research Foundation (DFG). The study will contribute to the historiography of port cities in the steam age, of the German and other empires, and to the current interdisciplinary debate about the Anthropocene.

After studying in Bochum, Glasgow, Paris, Oxford and Berlin, I wrote my first book on how the Nigerian Civil War (1967-1970), a Third World conflict that had initially been of marginal international interest, became a global media and protest event when the humanitarian crisis in Biafra aroused concern among publics around the globe. With my research, I have contributed to various much-discussed fields of study, notably the history of human rights, humanitarianism, post-colonial international, and Holocaust memory and comparisons from a global perspective. I revised the manuscript for publication as a monograph as a Postdoctoral Fellow in Human Rights at the University of California at Berkeley. The book was published with Cambridge University Press in 2017, and as a paperback in 2019.
