About me

Cliff Jones

I'm a Professor of Computing Science at Newcastle University with research interests ranging from theoretical computer science to dependability applications. I've spent over 20 years of my career in industry. My 15 years in IBM saw the creation of VDM which is one of the better known “formal methods“. For most people, their doctoral studies are “post graduate” qualifications — but I had no degree when Tony Hoare agreed, solely on the basis of my publications, to supervise my doctorate. From Oxford, I moved directly to a chair at Manchester University where we built a world-class Formal Methods group. During my time at Manchester, I had a five-year Senior Fellowship funded by the research council; later I also spent a sabbatical at Cambridge for the Newton Institute event on “Semantics”. In 1996 I moved back into industry with a small software company (Harlequin), directing some 50 developers on Information Management projects and finally became overall Technical Director before leaving to re-join academia in 1999 to take my current chair in Newcastle.

Much of my research focuses on formal (compositional) development methods for concurrent systems and support systems for formal reasoning. Major avenues of current research are listed below. I also retain a strong interest in the history of formal methods.

I am a Fellow of the Royal Academy of Engineering (FREng), ACM, BCS, and IET.

Reasoning about concurrent systems using rely/guarantee and separation logic.

If you think that you can build non-trivial sequential programs that satisfy their specification (have no "bugs") without formal methods, you are probably kidding yourself; but, if you are honest, you have have to confess that there is no chance with concurrent programs. Reasoning about concurrency is a major research challenge. Methods such as rely/guarantee thinking and (various) separation logics certainly help - but there is much more research required. We have an exciting pair of projects: (UK) EPSRC are funding "Taming Concurrency" on which Nisansala Yatpanage and Andrius Velykis are the post-Docs and the Australian Research Council is funding a project led by Ian Hayes with the title "Understanding concurrent programmes using rely-guarantee thinking".

Learning proof strategies from the expert.

(During and) since my time in IBM, I have had several tries at building support systems for engineers who are trying to use formal methods and I have used a number of systems developed by others (the first of which was Jim Kimg's "Effigy" system). Based on extensive industry industrial experience in the DEPLOY project, I developed the view that there was an unexplored way of using AI techniques. The AI4FM project was joint with Alan Bundy and his colleagues and explored how AI can be used to learn high-level strategies that are used by experts.

The funding for the AI4FM project has now finished but we are still working on a book that will collect the results.

Planning future infrastructures.

The "Infrastructure Transitions Research Consortium" is an EPSRC Programme Grant looking at the way in which crucial infrastructure systems will adapt to changes such as those that might be brought about by climate and population changes. Most of the resource in ITRC is focussed on the physical infrastructures (energy, transport, water and waste). Our involvement focuses on the interaction with ICT.

Logic of partial functions.

Partial functions are those that can fail to denote proper values for some argument combinations (one can say such functions and/or operators are undefined for some arguments). Partiality occurs frequently in the specification of computer systems and in attempts to prove formally that designs satisfy their specifications. The "Logic of Partial Functions" is a non-classical logic that makes such reasoning both sound and convenient. I continue to do research on LPF.

History of formal methods

History of formal methods (including collaboration with Peter Mosses' PLanCompS project). This includes making source material available on-line.

Although I do not limit my interest in formal methods to VDM, I do still try to stay abreast of such research and provide pointers to source material.

The EU-funded Rodin project enveloped methods and tool support for the Event-B method; the larger, industrial project DEPLOY was also EU funded and investigated the transfer of the methods and tools to our industrial collaborators. "Industrial Deployment of System Engineering Methods" is an important summary book.

Although I now spend most of my time doing research, I happen to love teaching. Apart from the occasional "guest" lecture on other courses, my main commitment at the moment is to CSC3321: Understanding Programming Languages.
