Marie-Lou is a legal scholar and a doctoral student in sociology at Princeton University, where she focuses on the socio-legal study of corporate finance, relations of debt and credit, and informational capitalism. Her current research combines quantitative and computational methods with doctrinal analyses to investigate how legal infrastructures construct the economy and to understand the distributional patterns and social consequences they generate.

She is a lawyer in Quebec (Canada), where she practiced in civil and commercial litigation. Before coming to Princeton, she studied the interaction of codified law and moral considerations in judges' reasoning, its relation to socioeconomic history, and its impacts on substantive law. Her LL.M. thesis (University of Montreal) combined comparative-historical and doctrinal analyses to theorize the emergence, scope, and purpose of judicially created barriers to legal action in Quebec private law.
