About Fatihcan M. AtayRifat SipahiSilviu-Iulian Niculescu

Rifat Sipahi received the B.Sc. degree (2000) from Istanbul Technical University Istanbul Turkey and the M.Sc. (2002) and Ph.D. (2005) degrees from the University of Connecticut Storrs CT all in mechanical engineering. Awarded with a Chateaubriand Postdoctoral Scholarship of the French Government he has been a postdoctoral fellow at HeuDiaSyC (CNRS) Labs at Universit'e de Technologie de Compi`egne France during 2005-2006. In 2006 he joined the Department of Mechanical and Industrial Engineering Northeastern University Boston where he is currently a Professor. His research interests include stability stabilization of dynamical systems at the interplay between multiple time delays and network graphs human-machine systems and human-robotic interactions.  He is the recipient of the 2015 ASME Dynamic Systems and Control Division Outstanding Young Investigator Award a 2011 DARPA Young Faculty Award 2022 College of Engineering Outstanding Faculty Service Award and 2014 College of Engineering Faculty Fellow Award. Among his involvement at various capacities in ASME IEEE and IFAC sponsored conferences/workshop he was the co-chair and Editor of 2022 IFAC Workshop on Time Delay Systems. Dr. Sipahi is currently an Associate Editor for Automatica. He is a Fellow of ASME and a Senior Member of IEEE. Silviu-Iulian Niculescu received his Ph.D. from INP Grenoble France in 1996. 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 the HEUDIASYC laboratory Compiègne France as a researcher at CNRS. 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 Gif-sur-Yvette where he is currently a research director (senior researcher) at CNRS. He was the head of the laboratory for a decade (2010-2019). Dr. Niculescu was awarded the CNRS Silver and Bronze Medals for scientific research and the Ph.D. Thesis Award from INPG Grenoble (France) in 2011 2001 and 1996 respectively. His research interests include delay systems robust control operator theory and numerical methods in optimization and their applications to the design of engineering systems. Fatihcan M. Atay received his Ph.D. in Applied Mathematics in 1994 from Brown University USA. He held positions in both academia and industry before joining the Max Planck Institute for Mathematics in the Sciences Leipzig Germany where he worked as Principal Investigator and the Coordinator of the research group Dynamical Systems and Network Analysis between 2002 and 2016. He is now Professor of Mathematics and Head of the Mathematics Department at Bilkent University Turkey. Fatihcan Atay is the author or co-author of over 100 peer-reviewed publications and the editor of a volume on complex time-delay systems. He is on the editorial board of  the Journal of Complex Networks and the Springer book series Advances in Delays and Dynamics. He has organized several international workshops and in 2012-2015 he coordinated an international consortium of several universities in the context of a large European project. His expertise and research interests are in the areas of dynamical systems delay-differential equations complex systems and networks.
