Ludmila Costhek Abílio is a senior researcher at the Centro de Estudos Sindicais e de Economia do Trabalho, the center for labor studies at the University of Campinas. Over the last twenty years she has focused on informal work and its relation to capitalist accumulation in the Global South. In her doctoral thesis, she investigated the work of the cosmetic resellers—more than a million women—who worked with one single company in Brazil, and more recently she has been tracking changes in the work of delivery couriers. This has seen her become one of the leading Brazilian authorities on the uberization of work. Her current research looks at uberization and the health of the just-in-time worker.
