    Research Director at CNRS


    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 and the head of the laboratory. (since 2010).

    He is author or co-author of ten books (Diderot: 1997; Birkhauser, Briefs: 2015; SIAM: 2007 and 2015; Springer: LNCIS - 2001, CES - 2014, AIC - 2015, SpringerBriefs - 2 in 2015  1 in 2016, and 1 in 2018)  and co-editor of six volumes (SIAM, 1999; Pergamon Press, 2001; Springer 2004; Springer 2007; Springer 2009).

He was the guest co-editor of five special issues in the area of delay systems (Journal of Mathematical Modelling of Natural Phenomena (MMNP) in 2009, Asian Journal of Control in 2005, IMA Journal of Mathematical Control and Information in 2002 and 2010, and Kybernetika in 2001).

    Dr. Niculescu has been scientific responsible of 15 international cooperation programs and projects (with Belgium, Mexico, Romania and Eastern European countries, South Korea, Hong Kong, Turkey and United States). He is member of the IPC of 45 International Conferences, and he was an Associate Editor of the IEEE Transactions on Automatic Control (2003-2005). Since 2011, he is an Associate Editor of European Journal of Controland IMA Journal of Mathematical Control and InformationIEEE Fellow since 2018, Dr Niculescu is the chair of the IFAC Technical Committee "Control Linear Systems" (TC 2.2) and he was the chair of the IFAC Research Group on "Time-delay systems" (2007 and chair of the IFAC Technical Committee on Control Linear Systems (TC 2.2) since 2017. Since 2012, he is the founding editor and the scientific responsible of the Springer (book) series: Advances in Delays in Dynamics (ADD@S).

    Dr. Niculescu was awarded the CNRS Silver and Bronze Medals for scientific research, the Best Paper Presentation Award at American Control Conference, Chicago, IL and the Ph.D. Thesis Award from INPG, Grenoble (France) in 2011, 2001, 2000, and 1996, respectively. He was also awarded the title of "Doctor Honoris Causa" of University of Craiova (Romania) in 2016. His research interests include delay systems, robust control, operator theory, and numerical methods in optimization, and their applications to the design of engineering systems.
