PHE Chromosomal Dosimetry Services

Research Gate profile

As a Higher Radiation Protection Scientist, Stephen is an experienced laboratory cytogeneticist with a particular interest in early radiation-induced DNA damage and repair using response markers including ƴH2AX and 53BP1. Stephen is part of the team of scientists carrying out biological dosimetry in the laboratory and its subsequent analysis. Stephen has been instrumental in carrying out PHE's work on a number of recent projects, taking responsibility for PHE's gamma-H2AX assay work for EU FP7 MULTIBIODOSE, EU FP7 RENEB and the current NIH CMCR RTGene and NIHR HPRU projects focused on biomarkers of exposure and effect for radiotherapy patients.

Stephen is also currently studying for a PhD research project investigating early lens changes in response to ionising radiation leading to radiation induced cataracts, in association with Durham University.
