Professor Alexander Romanovsky
Prof of Computing Science


Alexander (Sascha) Romanovsky is a Professor in the Centre for Software Reliability. He is the leader of the  Dependability Group at the School of Computing Science.

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

He received a M.Sc. degree in Applied Mathematics from Moscow State University and a PhD degree in Computer Science from St. 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.

In 1993-94 he was a post-doctoral fellow with the Department of Computing Science, University of Newcastle upon Tyne. In 1992-1998 he was involved in the Predictably Dependable Computing Systems (PDCS) ESPRIT Basic Research Action and the Design for Validation (DeVa) ESPRIT Basic Project. In 1998-2000 he worked on the Diversity in Safety Critical Software (DISCS) EPSRC/UK Project. Prof Romanovsky was a co-author of the Diversity with Off-The-Shelf Components (DOTS) EPSRC/UK Project and was involved in this project in 2001-2004. In 2000-2003 he was in the executive board of Dependable Systems of Systems (DSoS) IST Project.

In 2004-2007 he was the Coordinator of the FP6 ICT Rigorous Open Development Environment for Complex Systems Project (RODIN). In 2008-12 Prof Romanovsky  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.

He is now the Principle Investigator of the TrAmS-2 EPSRC/UK platform grant on Trustworthy Ambient Systems (2012-16) and of the  EPSRC/RSSB research project SafeCap on Overcoming the Railway Capacity Challenges without Undermining Rail Network Safety (2011-14).

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