Manuel Tonneau

Ph.D. student in Social Data Science, University of Oxford

Consultant, DIME AI, The World Bank

Member of the Open Networks and Big Data Lab, New York University





I am a second-year Ph.D. student in Social Data Science at the Oxford Internet Institute of the University of Oxford where I am supervised by Ralph Schroeder and Scott Hale. I also consult for the World Bank under the supervision of Samuel Fraiberger and am affiliated with the Open Networks and Big Data Lab at New York University.

My PhD research is focused on the moderation of online harmful content. Specifically, I study the extent to which such moderation may treat users unequally across geographies, from unequal automatic detection performance to unequal moderation enforcement through a potential misalignment between user preferences towards moderation and community guidelines.

Prior to the Ph.D., I worked as a research assistant at the World Bank and the Centre Marc Bloch on various computational social science projects. I hold an Engineering degree in Statistics and Economics (eq. to MSc) from ENSAE Paris as well as an MSc in Economics from Humboldt-Universität zu Berlin. My doctoral work is generously funded by a Global Merit Award from the Shirley Scholars Fund.
