Bill Karakostas was born in Greece. After graduating from University of Patras with a degree in Informatics and Computer Systems Engineering in 1986, Bill obtained an Mphil research degree in the Department of Computation, UMIST, in Manchester, UK in 1998 and a PhD in Software Engineering from the same Department in 1990. Since 1988 Bill has been working as a research assistant in various Esprit I and II projects investigating into new technologies for information system development (rule-based, temporal based etc). In 1990, Bill became a research fellow sponsored by UK electronics companies. In the same year, he became a lecturer in the Department-a post he held for 10 years. Between 1993 and 1995, Bill became the Technical Coordinator of Esprit III projects investigating system evolution and reuse. He also acted as Technical Editor for the European ESSI programme.

Between 1997 and 1999, he was the technical coordinator of another Esprit project investigating safety in the design of automotive telematics systems. In 1999, he became the Technical Coordinator of another Framework 5 project that researched into reference architectures for the shipping sector. In the same period, Bill acted as Evaluator of Framework 5 proposals in the areas of information management, software engineering, transport telematics, grid and cloud computing. Since 2000, Bill holds a Senior Lecturer appointment with the School of Informatics of City University, London. He is also an Associated Lecturer with the School of Engineering at the University of Surrey, UK. Bill has been a principal investigator in several projects investigating financial software technology transfer and survey of the state of the art, as well as becoming involved in preparation, evaluation and review of Framework 5 proposals and projects. Overall, in a career spanning over 20 years, Bill has collaborated in R&D projects with major European companies of the banking, automotive, aerospace and telecom sectors. Bill is an affiliate of IEEE Computer Society, an author of over 120 research publications, and an author/co-author of two books on requirements engineering and service systems engineering.
