His work has appeared in JACM, The Physical Review, TCS, Communications ACM, many IEEE and ACM Transactions , The Journal of Applied Probability, Advances in Applied Probability, The Computer Journal, Performance Evaluation, Management Science and other journals.

Awards: Erol is a Fellow of IEEE of ACM and of IET. He received the 2010 Oliver Lodge Medal for Achievement in Information Technology of the Institution for Engineering and Technology (London),  the 2008 SIGMETRICS Life Time Achievement Award  of the Association for Computing Machinery (New York), the 1996 Prix France Telecom of the French Academy of Sciences, the 1994 Parlar Foundation Award in Turkey, and honoris causa doctorates from the University of Liege, Belgium (2006), Bogazici University, Istanbul (2004),  and Univ. Roma II, Italy (1996). He was elected to Academia Europaea (2005), the Turkish Academy of Sciences (2007), the French National Academy of Engineering (2008), and as Foreign Member of the Hungarian Academy of Sciences (2010).

For his MSc, Erol worked on Tests for Finite-State Machines, developing an automated methods for generating finite test sequence using Regular Expressions. For his PhD he obtained properties  of Stochastic Automata that relate their structure to the families of languages that they recognise. From the early 1970's to the mid 1990's he helped develop the field of Performance Modeling and Evaluation of Computer Systems and Networks and created world class research groups at INRIA and at the University of Paris, as well as two PhD programmes.  In the mid-1980's he served as Science and Technology Adviser to the French Minister for Universities. During this time he introduced courses in Computer Science for all undergraduate majors in all disciplines across all the French Universities. He helped expand engineering, technical and vocational programmes in French higher education, he prepared measures which led to the introduction of independent PhD programmes in the grandes ecoles, and worked on reforms related to the "Ecoles Normales Superieures" in Paris, Lyon and Fontenay-StCloud. He also helped introduce incentives to encourage externally funded research programmes at universities and research institutes. From 1993 to 1998 he was Department Head at Duke University where he held an endowed chair and during his watch his department’s externally funded research was multiplied by four. From 1998 to 2003 he created the School of Electrical Engineering and Computer Science at the University of Central Florida and served as Associate Dean of Engineering, with direct supervision of four undergraduate programmes, three Master's and PhD programmes, with some 100 academic staff, and 2200 students including over 200 PhD students. He was responsible for growing substantially the undergraduate degree programmes and the PhD programmes. He was able to secure over $10M in funding for a new building, and expanded the externally funded research programmes by an order of magnitude. During his decade in the USA , Erol also conducted research that received funding from ARO, ONR, NSF and other federal agencies and industry that covered neural networks, image processing and video compression, augmented reality and simulation, and search techniques in unknown environments.

Since 2003, at Imperial College, his work on Self-Aware Networks, network security, energy savings in systems and networks, and biologically inspired computational models, has attracted funding from UK EPSRC, the European Union, the UK Ministry of Defence, the UK Technology Strategy Board, and several industrial partners including BT, QinetiQ, BAE Systems, General Dynamics, and collaborations with Telecom Italia, Northrup-Grumman and other partners.

Erol's research has covered various inter-related areas. In early work with co-workers, he proved that random access channels are intrinsically unstable and derived the explicit 1/n optimal throughput policy,and also contributed the first throughput analysis of data link control procedures such as HDLC. In the area of memory management, he provided analytical solutions for Markov models of paging algorithms, computed the optimum memory size allocation in virtual memory systems that use caching, and devised adaptive schemes for the management of multiprogrammed virtual memory systems. He also developped novel diffusion process models of multiprogramming systems, of queueing networks and wireless networks. The group he created at INRIA designed and implemented QNAP2 (also known as Modline), a Performance Modeling Package which incorporates methods that were invented at INRIA and at other research organisations; it is used worldwide and has been provided for a nominal charge to universities and used extensively as a commercial product by numerous organisations including BT. His other frequently cited work includes optimum checkpointing policies for data bases, and new product form queueing network models that incorporate control functions such as workload re-routing and work removal called "G-networks". G-Networks have also been used for Gene Regulatory Networks with further publications in journals and conferences in physics and biology. Erol also introduced the related random neural network (RNN) model of spiked neurons and its learning algorithms . One application has been the design of an "autonomic" packet network CPN: the cognitive packet network which uses neural networks in each node to make routing decisions.  Erol also investigates equilibria in large agent populations which may have collaborative or adversarial behaviours, as in biology, software agents, and interacting economic agents such as buyers and sellers in auctions. 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. Erol's journal papers can be found here. Many of his publications, PhD students, and collaborators are listed in the DBLP database. 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.

Erol is one of the founders of the field of computer system and network performance analysis. He first initiated and lead the Performance Modeling Groups at INRIA (France ) (1972-1982). He has published four books which have appeared in English. One of these was also published in French and Korean, while another one also appeared in Japanese. His contributions 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 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.

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 < < Jump 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.
