is a sociologist with attachments in France, the Netherlands and the United States. He teaches at the University of Lausanne. His research interests include migration, citizenship, gender, precarity, sexuality and social theory. After completing a collective study of migrant protests for legal status in France, he has been exploring the politics of mobility impacting people of various class and sexual backgrounds. Together with Olga Sezneva, he has begun a long-haul, unfinished effort to unpack the relationships between virtual goods, commodification, materiality and (im)mobility.
