Olivier Guéant

Olivier Guéant is a French mathematician, focusing on mean field game theory and financial mathematics. He is currently a Full Professor of applied mathematics at the Université Paris 1 Panthéon Sorbonne.

Background

Guéant studied mathematics and economics at Ecole Normale Supérieure[1] and also studied at Harvard. He defended the first PhD thesis on mean field games under the supervision of Pierre-Louis Lions. Guéant's PhD was awarded the Rosemont Demassieux prize.[2]

In 2010, along with Jean-Michel Lasry, Pierre-Louis Lions, and Henri Verdier, Guéant founded a start-up called MFG-Labs,[3] pioneering Big Data. The company was acquired by Havas Media in 2013.[4]

From 2010 to 2015, Guéant served as Associate professor in applied mathematics at Paris Diderot University. He then briefly served as Professor of Quantitative finance at ENSAE, and then accepted a Full Professorship of applied mathematics at the Sorbonne where he now serves.

His research on financial mathematics focuses on optimal execution and market making.[5] He also worked with Roger Guesnerie, Jean-Michel Lasry and Olivier David Zerbib on environmental interest rates.

Between 2014 and 2017, Guéant was sitting on the Scientific Advisory Board of Havas Media.

Financial Mathematics & Market-making

As an expert of financial mathematics and stochastic control, Guéant has published several books and articles on liquidity management, optimal orders execution and multi-asset market making.[6] He is also an expert on pricing and asset management. Along with Charles-Albert Lehalle and Joaquin Fernandez-Tapia, he notably solved the Avellaneda-Stoikov equations, which are key to dealing with inventory risk in market making.[7]
