Education

Philippe Poncet studied applied and pure mathematics at University Joseph Fourier of Grenoble (France), and graduated his Master 2 of Applied Mathematics in 1997. After one year of military obligations (CPGE of French Air Force Academy), he performed his PhD on particle methods for 3D flows in domains with curved boundaries. He joined the Toulouse Mathematics Institute (UMR CNRS 5219) in 2002, which resulted in his accreditation to supervise research (HDR) in 2008. He is full professor at UPPA since 2013, where he headed the team Numerical Methods and Complex Fluids at LMAP until 2018. Since this date, he is vice-president in charge of digital environment.
