His first book, Professional Climber: Creative work on the sponsoring labor market, was published by l’École des Hautes Études en Sciences Sociales in 2018 (EHESS, Paris). His second book, Impact work: An ethnographic journey into the craft of impact entrepreneurship, will be published by Palgrave MacMillan in 2024, and he recently co-edited The Professionalization of Action Sports published by Routledge in 2022.

Guillaume investigates drugs trafficking in its relationships with social, security, and health policies in Barcelona, Spain. Specifically, he studies ethnographically the phenomenon of the “Narcopisos”, namely the illegitimate occupation of public or private properties by criminal organizations to sell drugs as a dynamic. These narcopisos have emerged as an open-ended organizational response to the intensification of drug law enforcement, community pressure, harm reduction policies, and structural vulnerability.

Previous research has examined how structural digital inequalities shape access to the platform-mediated labor market and foster exclusion in the domain of employment and job searching; how entrepreneurs, impact investors, mentors, and leading corporations collaborate to create venture achieving social and commercial goals at a business accelerator; and how professional rock climbers strive to build their value on the sponsoring labor market by becoming creative entrepreneurs.

Guillaume has been a Visiting Professor or Researcher at the Department of Strategic Management at IESE Business School, the Digital Ethnography Research Center at RMIT, the Media Management and Transformation Center at JIBS, the Internet Interdisciplinary Institute at UOC, the Center for Research on Everyday Life and Work at UAB, and the Department of Sociology at CU Boulder.

Guillaume is an Anthropologist and received a joint PhD from the Autonomous University of Madrid and the University of Lyon. He previously conducted research as a Juan de la Cierva Fellow at the Autonomous University of Barcelona.
