Background
Erwan Le Saint has a dual background in engineering and economics, with both academic and professional experience in each field. He began his career as a structural engineer in engineering design offices before moving into economic strategy consulting as an economist.
This combination naturally led him to develop a strong interest in integrating both disciplines through economic modelling.
His work has focused extensively on energy and climate-related issues, while also extending to other sectors, including healthcare.
In 2017, his research thesis anticipated the economic slowdown of the European economy driven by increasing energy dependence. The study highlighted rising competitiveness risks, particularly compared with the United States, and advocated for the large-scale deployment of offshore wind capacity in the North Sea as a strategic mitigation measure.
