Postdoctoral Fellows

Introduction

​Mohamed Ghattassi received his Ph.D. degree in Applied Mathematics and Control Theory from the University Lorraine (IECL-CRAN, Université de Lorraine), France, in 2015. He subsequently spent a year at the University of Lorraine as a research and teaching assistant.  Since 2017, he is a Postdoc at the King Abdullah University of Science and Technology (KAUST) in the Computer, Electrical and Mathematical Sciences and Engineering Division (CEMSE). His research interests are in the area of modeling and numerical analysis of nonlinear PDE’s, control and observation of partial differential equations.​​​
