Islam Boussaada received his Master in Mathematics from University Tunis II, and an M.Sc. degree in Pure Mathematics from University Paris 7 in 2004. In December 2008, he defended his Ph.D. degree in Mathematics from University of Rouen Normandy. In June 2016, he received his HDR degree (French Habilitation) in Physics from University Paris Saclay-University Paris Sud. In 2010, IB was appointed for one year as a post-doctoral fellow in the control of time-delay systems at L2S, Supelec-CNRS-University Paris Sud. From September 2011 until September 2017, he has been an associate professor at IPSA and an associate researcher at MODESTY Team of L2S. Since October 2017, IB is appointed associate researcher at DISCO Team and full professor at IPSA where he headed the Aeronautical and Aerospace Systems department from September 2017 till May 2019. Since September 2018 untill August 2020, IB is a researcher in temporary secondment at Inria Saclay-DISCO Team. His research interests belong to the qualitative theory of dynamical systems and its application in control problems. It includes stability analysis and stabilization of linear/nonlinear dynamical systems, analysis of parametric systems, analysis of delay induced dynamics, nonhyperbolic dynamics, analysis of algebraic differential systems, control of active vibrations, dynamics of biochemical networks. IB is co-author of a monograph and co-editor of a contributed book, both published in Springer series, as well as co-author of more than 60 peer-reviewed publications. He co-organized the 4th GDRI DelSys’s Workshop on Observing and Controlling Complex Dynamical Systems (November 2015), as well as the 1st GDRI Spa-Disco’s workshop on Delays and Constraints in Distributed Parameters Systems (November 2017), both funded by CNRS and held at CentraleSupelec (Gif sur Yvette). IB is the co-organiser of several thematic/invited sessions in international conferences on the topic « Frequency domain methods for qualitative analysis of Time-delay Systems »; the 20th and 21st World Congress of the International Federation of Automatic Control (IFAC) (Toulouse, July 2017 & Berlin, July 2020), the 13th-15th IFAC Workshop on Time-delay Systems (Istanbul 2016, Budapest 2018 & Sinaia 2019) and the 24th International Symposium on Mathematical Theory of Networks and Systems (MTNS 2020) (Cambridge, 2021). Since September 2018, IB is co-leading the national research group GT OSYDI of the CNRS/GDR MACS and is a deputy director of the IRS iCODE Institute of the University Paris Saclay.
