The REF 2014 evaluation of British Universities recognised the Intelligent Systems and Networks group, which Erol headed from 2004-2016, as having "the highest proportion of world leading outputs" in Imperial's EEE Dept., and the EEE Dept. was Ranked 1st by REF 2014 in the field of Electrical & Electronic Engineering in the UK.
Erol Gelenbe pioneered and developed research on Computer and Network Performance in Engineering and Computer Science across Europe, which has won him numerous awards. He invented mathematical models such as G-networks, and the Random Neural Network and established their product-form asymptotic solutions. He has over 19,000 citations with H = 76, and graduated 77 PhDs including 17 women, placing him among the Top 25 supervisors of PhDs (worldwide all time) in the Mathematical Sciences (Mathematics Genealogy Project of the American Mathematical Society). He has conducted numerous industry collaborations leading to commercial products such as QNAP (Simulog, ASTEK), a software package for System Performance Analysis, the FLEXSIM (Flexsim) manufacturing system simulation tool, the SYCOMORE (Thales) Voice Packet Switch, and the C2Agents (QinetiQ) Command and Control Decision Aid.
Three of Erol's former PhD students were elected to their National Academies: the late Jacques Lenfant (Academie des Technologies, French National Academy of Engineering), Catherine Rosenberg (Canadian Academy of Engineering), Francois Baccelli (French National Academy of Sciences). Other former PhD students include Brigitte Plateau, current Director-General of Higher Education in france and former President of the University of Grenoble; Volkan Atalay, former VP and Provost of the Middle East Technical University, Ankara; Taskin Kocak, Dean of Engineering, Bahcesaray University, Istanbul; the late Jacques Lenfant served as President of the University of Rennes I in France.
Several of his former PhD students are industry leaders: Rakesh Kushwaha is founder and CTO of mFormation (sold to Alcatel), Vijay Srinivasan is CEO of Willow TV in California, Zhen Liu was founding director of the Nokia Lab in Beijing (later sold to Microsoft), Yutao Feng is VP of Ambarella Ltd in Shanghai (a video compression company).
Since 2006 he has graduated 18 PhDs at Imperial College and supervised numerous post-docs. Many are now academic faculty members -- mostly in Europe -- at the Universities of Uppsala, Cyprus, Kings College London, Napoli II, Greenwich, Houston (USA), or at Microsoft, Verizon, Alcatel, etc.
Described by E&T Magazine as a "true IT Innovator", Erol won IET's 2010 Oliver Lodge Medal in the UK. The ACM SIGMETRICS 2008 Life-Time Achievement Award awarded to Erol stated that he is "the single individual who, over a span of 30 years, has made the greatest overall contribution to the field of Computer System and Network Performance Evaluation". Other science awards include:
- 2013 "In Memoriam Dennis Gabor Award" of the Hungarian Academy of Science for outstanding science with significant innovation content, from the Hungarian Academy of Sciences (Gabor was the 1971 Nobel Laureate in Physics).
- 1994 Parlar Foundation Science Award of Turkey.
Erol has invented and obtained exact solutions, known as "product forms", to powerful mathematical models for complex system analysis, such as G-Networks and the Random Neural Network (RNN). Product forms correspond to cases where the mean fields provide exact solutions. G-networks and the RNN have non-linear mean fields.
He invented the Cognitive Packet Network patented in 2004, and the first Packet-Voice Network SYCOMORE. The team that he founded, trained and led in Paris, created Europe's first Network Performance Analysis Package QNAP commercialised by INRIA's spin-off SIMULOG.
For his services to Research and Higher Education, he was awarded honours by several European nations and Universities:
- Chevalier de la Legion d'Honneur (France, 2014), and Officier de l'Ordre du Merite (France, 2001), Chevalier des Palmes Academiques (France, 2003).
- Commendatore al Merito della Repubblica (Italy, 2005), and Grande Ufficiale dell'Ordine della Stella d'Italia (2007).
- Honorary Fellowships (Doctorate Honoris Causa) by the Universities of Liege (Belgium, 2006), Bogazici University - Istanbul (Turkey, 2004), and Rome II (Italy, 1996).
His current research addresses four related areas:
- "Autonomic" or self-aware and self-organising Software Defined Networks http://san.ee.ic.ac.uk including the Cognitive Packet Network.
- Energy Savings in ICT, in the Cloud and through Energy Harvesting for sensors in the Internet of Things (IoT) http://san.ee.ic.ac.uk
- Security in mobile networks; he was the coordinator (PI) of the EU FP7 Nemesys project (2012-2015) on Mobile Network Security http://www.nemesys-project.eu/nemesys/ - see also http://san.ee.ic.ac.uk.
- Reinforcement and Deep Learning with Random Neural Networks; in particular he investigates the effect of dense clusters of cells and of soma-to-soma interactions in neuronal circuits.
His work has also included analytical solutions to networked systems in engineering, physics and biology, including energy networks, neural networks, genetic networks, sensor networks and economic agents in the Internet.
His publications in the last 10 years appear in journals such as Physical Review, IEEE Networks, IEEE Trans. on Emerging Topics in Computing, IEEE J. of Selected Areas in Communications, Energies, ACM Performance Evaluation Review, IEEE Access, IEEE Trans. on Cloud Computing, Communications of the ACM, ACM Trans. on Sensor Networks, ACM Trans. on Internet Technology, Proceedings Royal Society, ACM Trans. on Adaptive and Autonomous Systems, IEEE/ACM Transactions on Bioinformatics and Computational Biology, IEEE Transactions on Nanobioscience, Neural Computation, The Computer Journal, etc.

Erol served as Science and Technology Advisor to the French Minister of Universities (1984-86). In 1982 he created a voluntary programme to provide Computer Technology education to unemployed people (Programme VFI) in France that served some 17,000 trainees over several years with the help of volunteers having engineering and computer science degrees. He serves on the board of several journals such as Acta Informatica, Performance Evaluation, Computational Management Science. Previous editorial boards include the Proceedings of the Royal Society (2006-2011), Proceedings IEEE (1994-1998), and The Computer Journal (2008-2012). He is currently General Chair for MASCOTS 2016.
Specific Details: Prof. Erol Gelenbe works on computer and network system performance evaluation methods and tools, and his work was incorporated into the QNAP2 commercial software package, and the design of FLEXSIM a commercial flexible manufacturing system simulator. His laboratory includes a large scale wired network test-bed, an ad hoc wireless network that incorporates power aware routing, wireless sensor networks, and a large scale distributed simulation tool DBES for emergency management. Recent industry collaborations include BT, BAE Systems, GD UK Ltd, QinetiQ, MBDA, Northrup-Grumman, Telecom Italia, Huawei.
Erol also introduced new computational models of biological systems, including the "Random Neural Network" and a probability model for Gene Regulatory Networks which includes temporal effects. The "Random Neural Network " has resulted in a patented technique for anomaly detection in Magnetic Resonance Images of the brain, and in the patented CPN algorithm for QoS routing in "autonomic" or self-aware adaptive networks (http://san.ee.ic.ac.uk), and in patents awarded for fast real-time distributed real-time decision making. Some of his recent work analyses the time that it takes to "search" when one has imperfect or wrong information about the location of the object that is being sought; this is relevant to wireless networks, to robotics and optimisation.
His early work contributed seminal results on the performance and implementation of random access multi-user communications and fibre networks, diffusion models of multi programming systems, adaptive performance of virtual memory systems, optimum checkpoints in databases, and the performance of database operations.
