Mathilde co-leads the data work for the Donor Tracker project. The Donor Tracker is a digital toolbox for global development advocates that brings more transparency to development funding and policies. It seeks to advance and support progress in global development by providing them with easy access to high-quality quantitative and qualitative strategic information to support their work. On top of dealing with methodological questions and data management, Mathilde uses her background in political sciences and public affairs to make sense of the data. Her portfolio includes France, Italy, Sweden, and Norway.

Mathilde is Associate Consultant at SEEK development. Besides working on the Donor Tracker, she conducts analysis of development policy and financing.
