Erol Gelenbe Erol Gelenbe FACM FIEEE FIEE is the Professor in the Dennis Gabor Chair, Electrical and Electronic Engineering Department, Imperial College London. He is a member of the Turkish Academy of Sciences, of Academia Europaea , and of theFrench National Academy of Engineering (Academie des Technologies) . His theoretical research develops and analyses probability models in the computer and information sciences. His group designs self-aware adaptive network protocols such as the Cognitive Packet Network , and tests them via large scale experiments, as part of European research projects on "Autonomic Communications" s upported by the EU FP6 Project CASCADAS and FP7 Project DIESIS. Erol also develops mathematical models of complex systems such as Gene Regulatory Networks, Chemical Reactions, Spiked Neural Networks, and Networked Auctions.

Erol made early research contributions to automata theory and the performance of paging algorithms for virtual memory systems. Then, he and his colleagues showed that random access channels are intrinsically unstable and that they have an explicit optimal stabilising policy; he has contributed the first throughput anayses of data link control procedures; he has developed novel diffusion models of multiprogramming systems and of wireless multi-hop networks; he has proved optimality criteria for checkpointing policies in data bases; he contributed adaptive control policies to avoid thrashing and maximise throughput in virtual memory systems; he has introduced new product form queueing network models that incorporate control functions such as workload re-routing and work removal called "G-networks". His has introduced models of spiked neurons and their learning algorithms with numerous applications including the design of an "autonomic" packet network (CPN: the cognitive packet network) which uses neural networks in each node for routing decisions. He also investigates equilibria in large agent populations which may have collaborative or adversarial behaviours, as in biology or with software agents. 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 both to wireless networks, to robotics and to optimisation. A list of Erol's journal papers can be found here. He is a graduate of METU, Ankara, and his publications and collaborations are also listed in DBLP. Erol has supervised over 57 PhD students, many of whom are prominent in academia, industry and government. He is active in funded research programmes in the UK and the EU, and in scientific organisations such as UKCRC and the Informatics Section of Academia Europaea. Erol was a founder of IFIP Working Group 7.3 (Computer System Performance Evaluation), ACM SIGMETRICS and of the journal Performance Evaluation. Since 1986 he has organised with the Turkish computer science and engineering community, the International Symposia on Computer and Information Sciences (ISCIS) which take place every year.

A founder of the field of computer system performance and network performance analysis he has published four books which have appeared in English, French, Japanese and Korean. His contributions to system performance evaluation include the introduction of Diffusion Approximations with adhesive boundaries and jumps (Journal ACM '75) to better approximate system performance at light and medium traffic ranges, which were used in the design of the Call Admission Control algorithm in IBM's N-way Stwitch for ATM networks (US Patent 2000), the first proof of the instability of random access communication channels and the design of a feedback control which stabilises and optimises their performance , the computation of optimal checkpointing times in database systems so as to maximise their availability in the presence of unpredictable failures, the invention of new queueing networks with "negative customers" which destroy work when they enter a queue (Journal Appl. Prob. '91) , showing that they have product form solutions, that the destruction of customers in these networks can have a "batch" form while the product form solution is preserved, and introducing new customer types such as "triggers" which displace customers between parts of the network. Thus "negative customers" are control signals that reduce congestion by destroying traffic in selected parts of the network, while "triggers" are signals which balance traffic in the network. Erol has introduced biologically inspired spiked and recurrent neural network models and learning algorithms and has shown that they have product form solutions. These models have proved useful in applications to texture recognition, combinatorial optimisation, to the modeling of neuronal sub-systems in animals and for the control of packet networks. Other recent work includes agent based simulation in conjunction with synthetic environments and augmented reality. He started and lead the Performance Modeling Groups at INRIA (France) (1972-1982).

Erol currently has three main research projects :
(1) Self-Aware Networks and Quality of Service investigates the use of neural networks together with biologically inspired techniques such as reinforcement learning and genetic algorithms, to control network behavior in real-time so as to provide users with the QoS that they request, and to improve network provide robustness and resilience. We are currently experimenting with these ideas on an 80 node Cognitive Packet Network test-bed at Imperial College. The new EU FP6 Project CASCADAS (2006-2009) on Autonomic Communications (with Telecom Italia and British Telecom) builds on these ideas, which are also being applied to autonomically detect and defend networks from denial-of-service attacks in the framework of the new HYPERION project being conducted jointly with British Telecom and UK MoD. We are also working on sensor networks in the framework of the new US/UK International Technology Alliance (2006-2016).
(2) Future Data Fusion Systems (2003-2009) is part of the Defence Technology Centre on Data and Information Fusion, and is supported by UK MoD and General Dynamics UK Ltd.
(3) Distributed Data and Information Systems (2005-2010)is a 5-year EPSRC funded project in collaboration with the Universities of Southampton, Oxford, Bristol and BAE Systems in which our group develops stochastic models of agents to study their equilibrium behaviour and system wide performance.

Lions, A.P. Ershov, G.I. Marchuk, W.J. Karplus, K. Samelson, F.H. Sumner). Elected membership of Eta Kappa Nu (Electrical Eng'g Honour Society) and Upsilon Pi Epsilon (Computer Science Honour Society). Meritorious Service Award of the IEEE (1989), and Meritorious Service Award of the IEEE Computer Society (1992).
Fellowships: Fulbright Fellow (from Turkey to the USA 1966-67) and NATO Science Fellow (1967-69) as a graduate student (1966-67), Gordon McKay Fellow at Harvard (1974).

Contributions: In the 1970's he designed virtual memory algorithms based on on-line adaptation from system measurements and provided some of the first exact analyses of page fault rates from program models. In the late 70's he co-authored the first analysis of Level 3 network protocols and the first exact proof of stability/instability of random access protocols; then his group designed and built the first fiber-optics random access network (XANTHOS) based on these access control algorithms. He patented a mini-packet based multi-processor switching fabric (SYCOMORE) which was built by the company LMT. He consulted for CNET (France) and helped France Telecom enhance its tele-traffic research activities by showing that traffic models could be effectively used to evaluate the performance. He also introduced diffusion approximations for queueing systems with holding times at the boundaries to improve approximation accuracy at both low and high traffic rates; this analysis was later used in a 1999 IBM U.S. Patent on Call Admission Control in ATM Networks. He was founding Vice-Chair of IFIP WG7.3 (Computer System Modelling and Performance Evaluation) and later served as its Vice-Chair and Chair for two separate six-year terms. He was also a co-founder of ACM SIGMETRICS and was active in ACM SIGOPS.
- In the 80's he published several books on computer performance evaluation , and wrote seminal papers on database performance including optimum checkpointing for reliability, resequencing of out-of-order updates, and analysis of the cost of relational operations. He served in Government from 1982 to 1986, but also graduated many PhD students and worked in the EU ESPRIT QMIPS project. He lectured at Ecole Polytechnique (1979-87), and Chaired the IEEE French Computer Society Chapter from 1981 to 1989.
- In the 90's, motivated by the spiking behaviour of natural neuronal systems, he introduced mathematical models for spiked recurrent random neural networks, developed their learning algorithms, and applied them to problems in image and video processing, object recognition, and on-line system adaptation. He proved that long-term properties of genetic algorithms can be computed in closed form. He invented new queueing networks with negative customers , and extended them to the case of signals and batch customer removal and to triggers and resets, he initiated the EU ESPRIT Project QMIPS (Quantitative Models of Information Processing Systems), and worked on the EPOCH and LYDIA projects. He showed that these queueing models, that are now known as G-networks , have "product form". In the 90's he was also awarded two U.S. patents, one for texture based image recognition and segmentation, and another for an ATM Network Call Admission Control (CAC) algorithm.
- More recently he introduced a Quality of Service (QoS) based "cognitive packet network" routing algorithm which has been implemented in wired and ad hoc wireless test-beds. He also works on QoS theory. He continues his research in queueing networks with product form , develops stochastic models of neural networks , and advanced simulation methods.
