Education & Career

Nikolay Tcholtchev holds a PhD. in engineering and a diploma degree in computer science from the Technical University of Berlin. He currently works for the Fraunhofer Institute for Open Communication Systems (FOKUS), where he conducts projects in the areas of Smart Cities (Open Urban Platforms), Data Platforms, Network and System Management, Cybersecurity, Autonomic Communications, Virtual and Softwarized Networks and Testbeds, VoIP Emergency Communication (NG112), Blockchain, Smart Energy, Firewall/IDS/IPS, Model Checking, IPv4/6, IoT, Artificial Intelligence, Model-based Testing and Testing for Critical Infrastructure Security Aspects, and Quantum Computing.

The current responsibilities of Nikolay Tcholtchev include the following activities: Team management of the group "Quality Engineering for Urban ICT and Quantum Computing", technical project management (industrial projects, Horizon Europe, H2020) and reporting (BMBF/BMWK, H2020, Horizon Europe, industrial projects) as well as project acquisition (BMBF/BMWK, Horizon Europe, industrial projects). He also supervises Master's and Bachelor's students in their theses on the above-mentioned topics. Nikolay Tcholtchev is a regular participant in international conferences and publishes regularly in conference proceedings and journals.

Nikolay Tcholtchev coordinates the BMWK EniQmA project, which is a consortium (consisting of the University of Stuttgart, DB Systel, IBM, FU Berlin and Fraunhofer) working on providing methods and tools for the systematic development of hybrid quantum-based systems and services.

In addition, Nikolay Tcholtchev is a recognized reviewer/assessor expert (for signalling, telecommunications and electrical engineering (STE)) of the German Federal Railway Authority with a focus on IT security within the framework of the projects bbIP (bahnbtriebliches IP-Netz) and DSTW (Digitales Stellwerk) of DB Netz AG. Furthermore, he was appointed by the responsible Federal Ministry to a science and innovation advisory board for the implementation of one of the major digitization projects in Germany. With his team, he has carried out a number of projects and studies for the scientific service of the EU Parliament and for the EU Commission, evaluating different technologies and their roles for the development of the European Union.
