Thomas Piketty (ENS, Doctor of Economics) is Director of Studies at the School of Higher Studies in Social Sciences (EHESS) and founder in 2006 of the School of Economics of Paris, which includes the Center for Economics at the Sorbonne (Paris 1 University), the former DELTA, CERAS and the Center for Economic Research and its Applications (CEPREMAP). He has taught at MIT and was a researcher at CNRS.  He specializes in economic and social inequalities from a historical and statistical perspective.

He is the author of eighteen books, the most notable of which are Capital in the 21st Century (2013), which has sold more than 2.5 million copies worldwide and been adapted into a documentary, as well as its sequel Capital and Ideology (2019). These studies have shown that the Anglo-Saxon countries, after having experienced the same decline in economic inequalities as the countries of continental Europe, have embarked on a dynamic of reconstitution of strong inequalities since the 1980s.

Several of his books have been reviewed by the Turgot Club.
