In a few words

Quang Huy Tran graduated from Mines ParisTech and completed his doctoral thesis in Applied Mathematics at IFPEN and Rice University (Texas) before returning to IFPEN as a research engineer specializing in Scientific Computing. His activities mainly focus on numerical methods for the approximate resolution of partial differential equations occurring in many physical models, and more incidentally on optimization. He holds a Habilitation to Conduct Researches degree and takes part in supervising several doctoral students. He is also in charge of Doctoral Training for the Division of Digital Sciences and Technologies and teaches in the Master 2 Analyse, Modélisation et Simulation of the University Paris-Saclay to which he is attached via the École Doctorale Sciences et Technologies de l'Information et de la Communication (STIC 580). His CV and list of works can be viewed on ORCID.
