Karine Côté-Boucher is Associate Professor of Criminology at Université de Montréal, where she directs the Master's program and graduate diploma in homeland security. Trained in sociology and anthropology, her current work pursues two interconnected questions: how automated decision-making and digital infrastructures reshape immigration governance, and how welfare and immigration regimes manage social reproduction amid global aging and care deficits. Together, these lines of inquiry reveal how borders reach into everyday life — shaping who receives care, who moves freely, and who belongs.
