Cancer affects all our lives, either personally or when a friend or family member falls ill. Many common cancers can now be treated with a relatively high success rate. One of the most effective forms of treatment is radiotherapy: the use of high energy x-rays or particle beams. These are very accurately targeted at a tumour with the intention of killing as many tumour cells as possible, whilst sparing the surrounding healthy tissue. Unfortunately, every patient and every tumour is unique. Therefore planning radiotherapy treatment presents a complex data science problem involving image analysis and a statistical simulation of the radiation beam and its interaction with biological matter to calculate dose.  I will describe a programme of work based at Cambridge involving clinicians, high energy physicists, computer scientists, engineers and mathematicians working together to improve the use of radiotherapy. We have addressed a wide range of practical issues in large scale data processing and computational simulation of tumour growth and treatment, with real impacts on patient care and the teaching of medical students. This uniquely interdisciplinary work is set in the context of the wider HPC and scientific computing environment in Cambridge. We host one of the largest academic supercomputers in the UK, pioneered the early development of cloud computing and run an internationally renowned course training the next generation of HPC and data scientists.


Current position
Director of eScience, Centre for Scientific Computing: September 2008-present previously Technical Director from November 2001

I was hired in 2001 to lead the day-to-day research and IT management at the Cambridge eScience Centre, which was one of the ten regional centres of the UK eScience programme. From its original purpose to support projects in Grid computing, the remit of the Centre expanded – as part of the Centre for Scientific Computing – to support a wide variety of computational science across the University of Cambridge. Its mode of operation has been to form long term collaborations, embedding within academic groups specialized expertise in scientific software engineering that they would otherwise find difficult to access. In recent years we have focused on work with the Department of Oncology in a series of projects based on Computational Radiotherapy. See for current work and for previous work.
