Toni Sayah, born in 1969, is a researcher and professor of mathematics at the Faculty of Sciences of Saint-Joseph University of Beirut (USJ), Lebanon. He was appointed as a assistant professor at USJ in 2000, promoted to associate professor in 2008, and then to full professor in 2013. He earned his engineering degree from the Lebanese University in 1993, followed by a DEA in numerical analysis from École Polytechnique in 1994. In 1998, he completed his Ph.D. at the Jacques-Louis Lions Laboratory (LJLL) of Pierre and Marie Curie University (Paris VI). His doctoral research focused on retarded potential methods for heterogeneous media and the approximation of thin layers using generalized impedance conditions in electromagnetism. In 2011, he obtained his habilitation to supervise research (HDR) in mathematics, also from Pierre and Marie Curie University, with a focus on the study of wave problems and fluid mechanics. At the Faculty of Sciences at USJ, Toni Sayah has held several administrative positions. He was the coordinator of the master's program Mathematics and Computer Science for Finance from 2002 to 2005, and later of the master's programs Actuarial and Financial Sciences and Numerical Analysis: Partial Differential Equations Option during 2005–2006. From 2006 to 2012, he served as the head of the Mathematics Department. Since 2014, he has been the director of the research unit Mathematics and Modeling. His research focuses on partial differential equations and numerical analysis. He has worked on integral equation methods for studying electromagnetic wave diffraction problems and on modeling, analyzing, and simulating various types of fluid problems (Stokes, Navier-Stokes, second-grade fluids, convection-diffusion-reaction problems, etc.), both stationary and non-stationary. Toni Sayah has supervised 16 doctoral theses and published 59 articles in peer-reviewed international journals.
