[16] He retired from Imperial College in 2019 to continue as Professor at the Institute of Theoretical and Applied Informatics of the Polish Academy of Sciences, Coordinator or Principal Investigator of EU H2020 Research and Innovation Project SerIoT (2017-2021) [17] on the security of the Internet of Things, the EU H2020 Research and Innovation Programmes SDK4ED (2018-2020) and IoTAC (2020-2023), and currently the EU Horizon Project DOSS (2023-2026). Active in several National Academies, he Chairs the Informatics Section of Academia Europaea since 2023 [7] . He served as SAPEA Advisor on Cybersecurity for the EU High Level Group (2017), Member of the Fake-News Study Group of the All-European Academies (ALLEA, 2020–2021) [18] , leader of the Science Communication (Diffusion des Sciences) Study Group (2020–21) of the Belgian Royal Academy of Sciences, Arts and Letters, and Study Group leader on "Research to Innovation in Europe" (2022) [19] of the Association of European Academies of Applied Sciences and Engineering.

The random neural network (RNN) is a mathematical representation of an interconnected network of neurons or cells which exchange spiking signals. It was invented by Erol Gelenbe and is linked to the G-network model of queueing networks as well as to Gene Regulatory Network models. Each cell state is represented by an integer whose value rises when the cell receives an excitatory spike and drops when it receives an inhibitory spike. The spikes can originate outside the network itself, or they can come from other cells in the networks. Cells whose internal excitatory state has a positive value are allowed to send out spikes of either kind to other cells in the network according to specific cell-dependent spiking rates. The model has a mathematical solution in steady-state which provides the joint probability distribution of the network in terms of the individual probabilities that each cell is excited and able to send out spikes. Computing this solution is based on solving a set of non-linear algebraic equations whose parameters are related to the spiking rates of individual cells and their connectivity to other cells, as well as the arrival rates of spikes from outside the network. The RNN is a recurrent model, i.e. a neural network that is allowed to have complex feedback loops.

In queueing theory, a discipline within the mathematical theory of probability, a G-network is an open network of G-queues first introduced by Erol Gelenbe as a model for queueing systems with specific control functions, such as traffic re-routing or traffic destruction, as well as a model for neural networks. A G-queue is a network of queues with several types of novel and useful customers:
In probability theory, a product-form solution is a particularly efficient form of solution for determining some metric of a system with distinct sub-components, where the metric for the collection of components can be written as a product of the metric across the different components. Using capital Pi notation a product-form solution has algebraic form
