Liz is a Ph. D. physics graduate with over 15 years of experience as a Radiation Protection Scientist at UKHSA's Chemical, Radiation Chemical and Environmental Hazards Division. As head of the Radiation Effects Department, Liz is responsible for a programme of research associated with understanding how exposure to ionising impacts health. Liz's main field of research is radiation biodosimetry - using the cytogenetic (cellular and chromosomal) effects of ionising radiation to estimate individual doses, and Liz also has wider interests in whole body radiation effects and non-cancer effects including cataractogenesis.

Jayne is a Ph. D. biology graduate with more than 30 years of experience as a Radiation Protection Scientist at UKHSA's Chemical, Radiation and Environmental Hazards.

Stephen has over 13 years' experience as a Radiation Protection Scientist at UKHSA and its predecessors. As head of the Cytogenetics Group and the Chromosome Dosimetry Service, Stephen's main field of research is radiation biodosimetry - using the cytogenetic (cellular and chromosomal) effects of ionising radiation to estimate individual doses. The service is further underpinned by Stephen and his colleagues' studies into the cytogenetic effects of ionising radiation and statistical methods to support research and development, and Stephen also has an interest in wider radiation protection, particularly whole-body radiation effects and radiation cataractogenesis.

Mingzhu has a research background in Biomaterials and Tissue Engineering including a number of publications and patents. She also has a wide range of knowledge and hands-on experience in Biomedical Sciences, such as cellular therapy and stem cells.

David started his academic career studying zoology in the University of Wales, successively in Swansea, Bangor and Cardiff as undergrad, post-grad and post-doc. He was then recruited by Andrew McLean and Geoff Dolphin to join the National Radiological Protection Board at its inception in 1971.
