Assessment of doses to the public from radionuclides discharged from nuclear power operations
I am the Scientific Adviser to the NERC TREE project ‘Integrating the science needed to underpin radioactivity assessments for humans and wildlife’.
In 2015 I was reappointed by the Marine Management Organisation to be one of their representatives on the Sussex Inshore & Conservation Agency Committee. www.sussex-ifca.gov.uk.
An annual budget of £3.5m, as the Head of the Science Unit in the Marine Environment Division from 1995 to 2007 in the Department for Environment, Food & Rural Affairs www.defra.gov.uk , working with c. 10 policy divisions with responsibilities for marine and freshwater matters. This included project appraisal and supervising over 60 R&D projects annually.
Prior to the London Olympics, Paul instigated a new environmental education and heritage initiative utilising the Marine Aggregate Levy Sustainability Fund www.marinealsf-navigator.org.uk. The total budget amounted to about £9m.
Universities have sought advice on the way to improve their chances of obtaining grants. Besides his Defra work, Paul has also been an Assessor for NERC e.g. Chaired a Knowledge Exchange meeting & been a Member of their Peer Review College. Other assessment duties have included work for the EU & Framework Programmes.

External Engagment and Impact
2015 ~ Member of the Board for the Journal of Radiological Protection.
Many ~ National e.g. via Visiting Professorships at Plymouth, Exeter and Brunel Universities. Other work has included lecturing on marine stewardship at Hull, Sheffield and Queen Mary London Universities + International e.g. in Hong Kong, USA & the EU.
Media work has included an Earth Watch programme on Radio 4 and helping David Attenborough. With Gavin Ross we covered an Environmental Crime Panel and Paul has worked with Channel 4 on a programme about the environmental impact of the Sellafield Nuclear Plant as well as providing advice to the Science Media Centre. www.sciencemediacentre.org/about-us.
I am a Visiting Professor delivering lectures on marine stewardship, EU policy and the delivery of science – based evidence.
