Research summary

In 1978 I started work on the design of a large water Cerenkov detector to search for proton decay and in 1980 I joined the IMB experiment. This was a 9000 tonne water detector located 2000ft underground in a large salt mine near Cleveland Ohio. Although proton decay was not discovered, neutrinos from the 1987A Supernova explosion were detected and anomalies were observed in the interaction of neutrinos originating from the upper atmosphere which may point towards neutrino oscillations.

Since the mid 1980's I have been working on the ZEUS e - p collider experiment firstly in its construction phase and then in running and analysis. My current analysis centers on the search for possible supersymmetric particles. I am als contributing to the design and construction of the ATLAS detector for the 14 Tev proton collider, the LHC, which will be running at CERN in 2005.

Teaching summary

The courses I have taught at UCL are Mathematics, Electricity and Magnetism and Thermal Physics in the first year and Mathematics, Electromagnetic Theory and Quantum Mechanics in the second year. I also teach courses on Electroweak Interactions and Deep Inelastic Scattering for the research students of UCL, QMW and RHBNC in the LIVENET series of lectures.


My introduction to elementary particle physics was in the sixth form of Newtown Grammar School in Montgomeryshire. I read a section on cyclotrons in one of G. R. Noakes's textbooks. Since there was a 1 Gev synchrotron in the Physics department of Birmingham University I decided to go there as an undergraduate and I stayed on as a research student and measured various nucleon nucleon interactions at 1 Gev. In 1965 I became a CERN Fellow and worked on an experiment to measure the beta decay of the Xi particle. The result was important in confirming the Cabibbo theory of charged current semi-leptonic weak interactions of the hadrons.

After coming to UCL in 1968 I worked for ten years in the Bubble Chamber Group mainly on the Gargamelle neutrino experiment. Highlights of this programme were the discovery of the weak neutral current and the confirmation of the quark substructure of the nucleons.
