Sami Erol Gelenbe (born 22 August 1945, Istanbul) is a Turkish and French computer scientist, electronic engineer and applied mathematician, renowned for pioneering work in computer system and network performance.
A Fellow of several national academies, Gelenbe has chaired the Informatics Section of Academia Europaea since 2023.
Biography
Erol Gelenbe is the son of Yusuf Âli Gelenbe and Maria Sacchet Gelenbe. His father was a descendant of the 18th-century Ottoman mathematician Gelenbevi Ismail Efendi and nephew of the Ottoman Sheyhulislam Mehmet Cemaleddin Efendi. Erol graduated from
Ankara Koleji and the Middle East Technical University, Ankara, where he won the K.K. Clarke Research Award for his undergraduate thesis on "
partial flux switching magnetic memory systems".
Awarded a Fulbright Fellowship, he completed a master's degree and Ph.D. at the Polytechnic University on "Stochastic automata with structural restrictions" under Prof. Edward J. Smith.
Career
Immediately after his PhD, he joined the University of Michigan in 1970 as an assistant professor. He was granted a leave of absence from the University of Michigan in 1972 to found the
Modeling and Performance Evaluation of Computer Systems research group at
INRIA (France), and was also a visiting associate professor at Paris 13 University. He was elected to a chair in Computer Science at the University of Liège (Belgium) and appointed in 1973, joining Professor Danny Ribbens while remaining a research director at INRIA. He was awarded a
Doctorat (November 1973) from Sorbonne University, with a thesis on "
Modèlisation des systèmes informatiques", under Professor Jacques-Louis Lions. He remained a close friend of Professor Ribbens and of the University of Liège, but moved to the Paris-Sud 11 University in 1979, where he co-founded the Laboratoire de Recherche en Informatique and its Ph.D. Program, before joining Paris Descartes University in 1986 as founding director of the Ecole des Hautes Etudes en Informatique.
Gelenbe was appointed New Jersey State Endowed Chair Professor at the New Jersey Institute of Technology (1991-1993). He joined Duke University in 1993 and was appointed Nello L. Teer Chair Professor and Chair of Electrical and Computer Engineering. In 1998 he moved to the University of Central Florida to create the School of Electrical Engineering and Computer Science creating the Harris Corporation Engineering Centre.[.] In 2003 he was offered the Dennis Gabor Chair at Imperial College London
