Definition
Olivier Guéant is a French mathematician and academic researcher known for his contributions to mathematical finance, particularly in the areas of optimal execution, market microstructure, and stochastic control.
Overview
Guéant holds a professorial position in the Department of Mathematics at the University of Paris‑Dauphine, where he teaches and conducts research on quantitative finance. His work focuses on developing rigorous mathematical models for the execution of large orders in financial markets, the impact of trading on asset prices, and the design of optimal trading strategies. He has published extensively in peer‑reviewed journals and conference proceedings, and he is the author of several monographs, including The Financial Mathematics of Market Liquidity (Cambridge University Press, 2019). Guéant is a frequent speaker at international conferences on quantitative finance and has collaborated with both academic institutions and industry practitioners.
Etymology/Origin
The surname Guéant is of French origin, derived from regional linguistic variations of names such as Geant or Géant, meaning “giant” in French. The given name Olivier is a common French masculine name, historically linked to the medieval name Olive and associated with the olive tree, symbolizing peace.
