Economists, Analysts and Data-Scientists

Our economists, analysts and data-scientists are recognised experts in their field. Most of them are engaged in academic activities with teaching assignments, usually at Master’s degree level, in their respective areas of specialization. They are also regularly solicited as Jury members for PhD dissertations.

In June 2023, Sandrine Lunven, now CEO, took over the position from Sylvain Barthélémy, who has decided to devote his talents and energy to the rapid advances in Artificial Intelligence (AI) techniques. For this purpose, he created a dedicated company, Gwenlake, while remaining partner and technical advisor to TAC ECONOMICS.
