Dan Lumley, Lead Radiographer
Daniel joined the Gamma Knife team as the Senior Radiographer in 2009 and became the Lead Radiographer in 2014.
Having earned a First Class Honours degree in Radiotherapy and Oncology from Sheffield Hallam University Daniel worked as a Therapeutic Radiographer within the Midlands, specialising in Treatment Simulation and Planning, Brachytherapy treatment delivery and Infection Control management.
Since joining the Gamma Knife Centre Daniel has continued to enhance his Professional Development, undertaking specialist Stereotactic Radiosurgery training in Stockholm.
Nimrah has recently joined the Gamma Knife team. She graduated from Glasgow Caledonian University in Radiotherapy and Oncology in 2011 and worked in both public and private sectors in London gaining a wealth of experience working across both radiotherapy treatment and planning. Nimrah has several years experience working as a Senior Radiographer within the Gamma Knife Centre at the Bupa Cromwell Hospital.

Ian Paddick, Consultant Physicist
Ian began his career as a Medical Physicist in 1989, working at the Hammersmith hospital, London. Since 1998 he has worked almost exclusively with the Gamma Knife, being responsible for over 3,000 patient treatments using the B, 4C and Perfexion Gamma Knife models.
He is a regular speaker and moderator at Radiosurgery conferences, teaching on training courses and helping start up new Gamma Knife centres worldwide.
He is on the scientific committees of the International Stereotactic Radiosurgery Society and the Leksell Gamma Knife Society and is currently vice president of the International Stereotactic Radiosurgery Society . His publications in Radiosurgery have established him as an authority in Radiosurgery dose planning. In 2003, Ian became a freelance physicist, providing physics services to Gamma Knife centres in the UK and USA, as well as the manufacturers of the Gamma Knife; Elekta Instruments. In 2009 he published “Radiosurgery Treatment Planning”, the first book covering practical techniques of dose planning.
Phil Tapper, Physicist
After graduating in Physics & Astrophysics from Queen Elizabeth College, London Phil trained in Radiation Physics at the Medical College of St Bartholomew’s Hospital which led to the award of an MSc in 1985.
After working in Radiation Protection for about 2 years he transferred to Radiotherapy at The Middlesex Hospital in 1988. He worked there for 5 years before moving on to the Royal Marsden NHS Trust in Fulham where he spent a further 6 years in Radiotherapy. These NHS posts gave Phil a thorough grounding in all aspects of radiotherapy physics within large teaching hospital environments.
In 1999, Phil moved into the private sector as Deputy Chief Physicist at The Harley Street Cancer Centre, a facility of the HCA International group of hospitals. Within a year he had been promoted to Chief Physicist and carried on to head the Medical Physics Department for a further 8 years. During his time at HSCC he oversaw the expansion of prostate seed brachytherapy and radionuclide therapy as well as the development of the Radiotherapy Department into a nationally recognised site of clinical excellence. More pertinently, in 2006, HCA International took over the London Gamma Knife Centre, and Phil’s department provided the physics support to this new facility. During his tenure he treated over 250 radiosurgery patients on the C and then the 4C models of the Leksell Gamma Knife system. By the time Phil left HSCC his department was bringing in annual revenues in excess of £1m.
In September 2008 Phil left HSCC and set up his own company, “pdt Dosimetry Services Ltd.” Since then, he has been providing radiosurgical physics support, as a consultant, to the Gamma Knife Centres at BMI Thornbury Hospital in Sheffield and the Bupa Cromwell Hospital in London. Both Centres have Perfexion, the latest Leksell Gamma Knife, and Phil has already treated in excess of 350 patients using this system.
After graduating in Physics & Astrophysics from Queen Elizabeth College, London Phil trained in Radiation Physics at the Medical College of St Bartholomew’s Hospital which led to the award of an MSc in 1985. He then worked for a number of years in the NHS before moving into the private sector, eventually becoming Head of the Medical Physics Department including the London Gammaknife Centre at the Harley Street Cancer Centre.
Since 2008 he has providing radiosurgical physics support as a consultant, to the Thornbury Gammaknife Centre and the Gammaknife Centres at the Bupa Cromwell Hospital in London. He has treated in excess of 700 patients using the Gammaknife.
