  Career Summary

  1980-89 Central Electricity Research Laboratories

  Part of team which designed and implemented one of the first distributed real time databases for use within industrial process control systems. I was responsible for the database schema processing. Papers describing this system were presented at the BNCOD series of conferences and IEE events.

  I was responsible for the design, construction and testing of a computer system to monitor the interlock system at Dinorwig pump storage power system (the UK's only major ``on-demand'' electricity generation system). The 18KV subsystem is one of the more complex, comprising twin busbars, 6 pump/generators and twin startup plant all with isolators and breakers. There had been significant design problems with the original interlock system which was relay based.

  1989-93 Logica

  1992-93 - British Gas Exploration and Production

  Whilst with Logica I led the team which enhanced British Gas' Company Office System (COS) and customised it for use in the USA including installing it at BG's USA oil head quarters in Houston, Texas where it was used by 200 staff.

  Following this success I was the technical co-ordinator for the combined BG/Logica team which rolled out the new version of COS at another 4 sites and two offshore gas fields (500 users, 335 new or upgraded PCs, 60 km of cables).

  1989-92 - British Gas South Eastern

  Leader of the team which designed, implemented, tested and installed the telemetry interface for a new geographically distributed regional control system. Eventually becoming project manager and saw the system accepted and paid for by the customer. This system controls the gas supply to more than 2 million customers through 16,000 miles of pipes, it was delivered on time and made substantially more than planned profit.

  1993-96 PhD University College London

  Before I joined UCL Computer Science department in October 1993, I decided to change my career from practising software engineering to research of it. For my PhD [1] I studied evolutionary computational techniques, investigating their use to solve real world problems and the importance of abstract data structures to them.

  I undertook research into how software engineering techniques, such as data abstraction, can benefit evolutionary computation [66,10,67]. Data abstraction is very powerful, for example it enables real software to be constructed using abstract data models such as ``files'' which enable real physical devices (e.g. spinning iron oxide) to be used with no knowledge on the part of the ``high level'' programmer. I showed some examples where abstract data types are indeed beneficial to problem solving using evolutionary computation.

  I worked with The National Grid Company plc. to solve one of their major scheduling problems; planning the maintenance of the UK's high-voltage electricity network [68,12,69].

  Whilst at UCL I was also involved with undergraduate teaching and supervision of MSc. students, some of whom have also worked with The National Grid Company plc.

  I created and now maintain the GP bibliography [11]. Finally I was the PhD students unofficial social secretary, organising lunches, after hours events as well as more formal seminars and presentations.

  1996-98 RF University of Birmingham

  Following my PhD I started work as a research fellow within the School of Computer Science at the University of Birmingham. I critically investigated genetic programming (GP) in order to assess its future applicability to multi-agent simulations.

  I developed a quantitative model of GP performance in one benchmark problem [70]. In another, I highlighted GP's surprisingly poor performance and used fitness landscape and building block analysis to suggest why this might be so [75]. Other investigations have considered the problem of growth in code size in GP, stressing the importance of the fitness function and showing other evolutionary techniques also have the same problem [71,141,72,73,74].

  We also produced a schema theorem for GP [41,112,115] and new types of crossover [111] as well as highlighting aspects of the existing GP crossover operator [113,114].

  I was also active in the EEBIC group, organising and giving seminars and creating the award winning EEBIC www demonstration pages. These include Java demonstrations of genetic algorithm maintenance scheduling. I also supervised advanced MSc students (e.g. [160]).

  1998-2000 CWI, Amsterdam

  In the Evolutionary Systems and Applied Algorithmics group (SEN4) I investigated evolutionary algorithms, particularly their application within multi-agent systems for e-commerce and economic simulations, Internet trading, user profiling and data mining (road safety, natural language processing etc.). Investigation of n-grams for natural language text classification showed they are in themselves very powerful and could achieve results on a par with a much more sophisticated (and computer resource intensive) technique [146]. I also applied GP to a mixed commercial dataset of insurance data. On entering the Benelearn'99 data mining competition GP had the highest score of the automatic techniques entered (coming third after two human data mining experts guiding semi-automated techniques) [163].

  I continued my theoretical studies of evolutionary computation [76,21,22,145,79].

  I organised the group's seminars (34, including 8 from international speakers) and have supervised master students [118].

  While based at CWI, I visited both Dortmund University [80] and Chalmers University in Göteborg [78]. Including giving a ``Guest Lecture'' based on my book to undergraduates.

  2000-2003 Senior Research Fellow, University College London

  I worked on the Faraday INTErSECT project on Intelligent Data Analysis and Fusion Techniques in Pharmaceuticals, Bioprocessing and Process Control. and followup EPSRC RAIS secondment with GlaxoSmithKline's Data Exploration Sciences group. There are many such data mining techniques. Indeed some are commercially available. However the intelligent application of them remains an art rather an automated process. Similarly it is not clear how to use them in combination or fuse their results. I showed the use of evolutionary approaches to combining classifiers, particularly for pharmaceutical data mining.

  During Summer 2000 I visited Chalmers University in Sweden for a second time and worked with them on their prototype, human like robot, Elvis. We concentrated on Elvis learning to integrate its stereo vision with its arm actuators [82]. During the spring of 2004 I visited Memorial University in Canada [28].

  I continued my theoretical studies of evolutionary computation [2], did some consultancy work and assessment.

  2004-2006 Research Fellow, University of Essex

  I was the senior research assistant on the EPSRC's eXtended Particle Swarm XPS optimisation project. We have been both mathematically analysing existing PSO and proposing improvements. We used GP to propose new optimisation test benchmarks and evolve novel specialised PSOs.

  2006-2008 Research Fellow, University of Essex

  BBSRC project on data mining Affymetrix GeneChip datasets to investigate alternative splicing, principally in humans. Created tools for detecting defects in tens of thousands of GeneChips and discovered systematic problems in GeneChip probe design (runs of Guanine etc.). Created which provides immediate online access to cleaned up mRNA measurements for all Homosapien genes and analysis tools to investigate gene expression and co-expression.

  2008-2010 Research Fellow, King's College, London

  I applied genetic search to Software Engineering, in particular to higher order mutation testing. More recent work includes using grammar based GP to re-engineer nVidia CUDA software.

  2010- Research Fellow, University College, London

  Very shortly the whole CREST group will move to UCL. I will extend my GISMO research on evolving improved software components of larger systems.
