Lisa Richaud is FNRS Post-doctoral fellow in social anthropology at the Université Libre de Bruxelles. Previously, she worked as a post-doc researcher at Fudan University and King’s College London on the ESRC-NSFC project ‘Migration, Mental Health and the Chinese Mega-City’. She is the editor of a special section in HAU: Journal of Ethnographic Theory on the politics of negative affects in post-Reform China (to be published by the end of 2021). Based on her doctoral research, her monograph in preparation focuses on the collective performance of Maoist tunes by Beijing parkgoers, asking what happens when a practice once designed to produce socialist commitment is reframed as casual.
