Emmanuel Lepinette

Emmanuel Lepinette is a distinguished researcher in applied mathematics, focusing on finance and economics at CEREMADE (Centre de Recherche en Mathématiques de la Décision), a CNRS research unit (UMR 7534) based in Paris, within the PSL National Research University. His academic endeavors are primarily concentrated on financial market models with transaction costs, delving into areas such as pricing, arbitrage theory, stochastic calculus, and financial market modeling. Additionally, he explores random preference relations, random sets, and risk measures.

Lepinette is an active member of the RGOSA (ex GOSAEF) research group in Tunis, contributing to the international academic discourse on finance and economics. He holds a position as a teaching researcher at Université Paris Dauphine, part of Université PSL, where his office is located at Bureau B518ter. He can be contacted by phone at +33(0) 1 44 05 49 39 or via email at emmanuel.lepinette@ceremade.dauphine.fr.
