Présentation

**Silviu-Iulian NICULESCU** was born in Petrosani, Romania in 1968. He received the B.S. degree from the Polytechnical Institute of Bucharest, Romania, the M.Sc., and Ph.D. degrees, both in Automatic Control, from the Institut National Polytechnique de Grenoble, France, and the “Habilitation à Diriger des Recherches” (HDR) in Automatic Control from Université de Technologie de Compiègne, in 1992, 1993, 1996, and 2003, respectively. From 1992 to 1997, he was with the Department of Automatic Control and Computers, University "Politehnica" Bucharest, Romania. From 1997 to 2006, he was with HEUDIASYC (“Heuristics and diagnosis of complex systems”) laboratory, Compiègne, France as a Researcher at CNRS (French National Center for Scientific Research). He also held a PostDoctoral position in the Department of Applied Mathematics, ENSTA, Paris, France, from 1996 to 1997. In September 2006, he joined L2S (Laboratory of Signals and Systems), Gif-sur-Yvette, where he is currently ***Research Director*** (“Senior Researcher”) ***at CNRS.*** He was the ***head of the laboratory*** for 10 years (2010-2019). Co-founder of the ***Inria team "DISCO"*** (common team of Inria with CNRS and CentraleSupélec, located at L2S) in 2010, he is also an active member of the team. Dr. Niculescu is author or co-author of ***eleven books*** (Diderot: 1997; Birkhauser, Briefs: 2015; SIAM: 2007, 2014 and 2021; Springer: LNCIS - 2001, CES - 2014, AIC - 2015, SpringerBriefs - 2 in 2015 1 in 2016, and 1 in 2021) and ***co-editor*** of ***six volumes*** (SIAM, 1999; Pergamon Press, 2001; Springer 2004; Springer 2007; Springer 2009).

He was also awarded the title of *"Doctor Honoris Causa"* of University of Craiova (Romania) in 2016 and University Dunarea de Jos, Galati (Romania) in 2023. His research interests include delay systems, robust control, operator theory, and numerical methods in optimization, and their applications to the design of engineering systems.
