Biography

Mathias is a DPhil student whose research straddles development and environmental economics. His methodological focus lies on applied econometrics, inferential statistics, and spatial data analysis. For his DPhil, he uses observational study designs and simulation methods to jointly evaluate the economic, social, and environmental effects of scaling key agricultural technologies, like improved seeds or fertilisers, across countries in Sub-Saharan Africa.

Mathias holds a B.A. in European Studies, an M.Sc. in Public Policy and Human Development, and an M.Sc. in Economic and Financial Research. Before starting his DPhil, Mathias worked with the Development Economics Group at ETH Zurich (2021-2022) and on the Climate Compatible Growth programme at the Smith School of Enterprise and the Environment (2023-2025). Mathias’ DPhil is funded by the ECI African Food Programme Scholarship.
