Islam Boussaada is a Full Professor at IPSA, a leading French engineering school specializing in aeronautics and aerospace. He is also an associate researcher at the Laboratory of Signals and Systems (L2S) – Université Paris-Saclay, CNRS, CentraleSupélec – and with the DISCO team at Inria Saclay, where he was on research secondment from 2018 to 2020.
He received his Maîtrise in Mathematics from the University of Carthage (Faculty of Sciences of Bizerte) in 2003, an M.Sc. (DEA) in Pure Mathematics from Université Paris Cité in 2004, a Ph.D. in Mathematics from the University of Rouen Normandy in 2008, and his Habilitation à Diriger des Recherches in Physics from Université Paris-Saclay in 2016.
His research focuses on the qualitative theory of dynamical systems and partial differential equations, with applications in control theory—particularly time-delay systems, parametric and non-hyperbolic systems, and the control of vibrations. He is co-author of a monograph, co-editor of two contributed volumes, and has authored more than 150 peer-reviewed publications. He also leads the P3δ project, dedicated to delay-based control design.
Prof. Boussaada has organized several international workshops and thematic sessions at major conferences. He served as IPC Co-Chair of the IFAC Workshop on Time-Delay Systems 2024 in Udine, Italy, and is currently Co-General Chair of the IFAC Joint Conference 2025 to be held in Gif-sur-Yvette, France, which includes the 9th Symposium on System Structure and Control (SSSC), the 19th Workshop on Time-Delay Systems (TDS), and the 2nd Workshop on Control of Complex Systems (COSY).
From 2018 to 2023, he co-led the national research group GT OSYDI, and from 2019 to 2021, served as Deputy Director of the IRS iCODE Institute at Université Paris-Saclay, and from 2019 to 2025, served as member of administration council of SAGIP. In 2024, he was named laureate of the CNRS–Africa Joint Research Program for the project SPECTRE-EDP, in recognition of his contributions to international research collaboration in mathematical control theory.
