Professor Alexander Romanovsky

Emeritus Professor


Alexander (Sascha) Romanovsky is Emeritus Professor and Senior Research Investigator at Newcastle.

His main research interests are system dependability, fault tolerance, safety, software architectures, exception handling, error recovery, system verification for safety, system structuring and verification of fault tolerance and safety.

He received a M.Sc. degree in Applied Mathematics from Moscow State University and a PhD degree in Computer Science from Saint Petersburg State Technical University. He was with this University from 1984 until 1996, doing research and teaching. In 1991 he worked as a visiting researcher at ABB Ltd Computer Architecture Lab Research Center, Switzerland. In 1993 he was a visiting fellow at Istituto di Elaborazione della Informazione, CNR, Pisa, Italy. In 1993-94 he was a post-doctoral fellow with the Department of Computing Science, University of Newcastle upon Tyne, UK.

Since 1992 Prof Romanovsky has been involved in a number of EC and UK research projects on various aspects of system dependability engineering.

In 2004-07 Prof Romanovsky was the Coordinator of the FP6 ICT Rigorous Open Development Environment for Complex Systems Project (RODIN). In 2008-12 he was the Coordinator of the major FP7 Integrated Project on Industrial Deployment of System Engineering Methods Providing High Dependability and Productivity (DEPLOY). The DEPLOY IP, that followed RODIN, developed the Rodin tooling environment for formal stepwise design of complex dependable systems using Event-B. Rodin is now widely used by companies in Europe, China, Japan, Canada and Brazil.

Prof Romanovsky is now the Principle Investigator of the EPSRC STRATA platform grant on Layers for Structuring Trustworthy Ambient Systems (2016-21).

He is leading several projects on formal verification of railway safety supported by the UK industry. The focus of this work is to develop scalable and usable industry-strenght techniques for fuly automated verification of signalling and interlocking.

Prof Romanovsky is a visiting professor at the National Institute of Informatics (NII, Tokyo, Japan).


Our work now manly focuses on modelling and verification of railway systems - follow it on the SafeCap web site.

Research interests: 

  • fault-tolerance software: system structuring, error recovery
  • rigorous development of fault tolerant systems (RODIN, CORRECT and DEPLOY projects)
  • refinement and modelling patterns (DEPLOY, RODIN, TrAmS and TrAmS-2 projects)
  • engineering of dependable mobile systems (the RODIN project)
  • a middleware for building fault tolerant mobile systems (the CAMA system)
  • fault tolerance of service oriented architectures and web services
  • dependability-explicit and resilience-explicit computing
  • the WS-Mediator architecture for dependable WS integration
  • exception handling (a list of papers and reports on this topic )
  • fault tolerance software architectures (including a one-day tutorial – given at WICSA 2007, ISSRE 2007 and SAFECOMP 2008)
  • software diversity (DeVa, DISCS and DOTS projects)
  • fault tolerance of concurrent and distributed systems; conversations, atomic actions and atomic transactions
  • Coordinated Atomic Actions in the DeVa and DSoS Projects, and beyond
  • dependability of systems employing legacy code and of complex systems of systems (the DOTS and DSoS projects)
  • dependability in the component-based system development and protective wrapping (the DOTS project).
