Biography

Biography

Paddy Regan joined the academic staff in the Physics Department at Surrey in 1994 after holding postdoctoral research positions in experimental nuclear structure physics at the University of Pennsylvania, USA and the Australian National University in Canberra. He was subsequently promoted to Senior Lecturer (2002), Reader (2005) and a Personal Chair in Experimental Nuclear Physics (2009).

Since 2013, he has held the NPL-Surrey Chair in Radionuclide Metrology and is part-based within the Nuclear Metrology Group at the National Physical Laboratory (NPL) in Teddington where he is the Science Area Leader.

He has co-authored over 300 peer-reviewed scientific papers on nuclear physics and radiation detection/instrumentation research and given more than 100 invited international conference and workshop presentations on his research.

Paddy was elected a Fellow of the Institute of Physics in 2000. From 2002-2013, he held Visiting Research positions in Experimental Nuclear Physics at the Wright Nuclear Structure Laboratory, Yale University and was also an Adjunct Professor in Physics at the University of Notre Dame (Indiana, USA) on their UK-London Programme providing pre-medical physics courses  to their London-based students.

From 2001 until 2010, he was the Collaboration Spokesperson for the Stopped RISING Collaboration (https://doi.org/10.1016/j.nimb.2007.04.219 ). As part of this role, he led experimental studies on the internal structure of exotic forms of atomic nuclei using both metastable state spectroscopy for studies of the heaviest odd-odd N=Z nuclear systems ( https://doi.org/10.1016/j.physletb.2008.01.017 ) and beta-decay delayed, time correlated gamma-ray spectroscopy for nuclear shape evolution studies in the heaviest Osmium ( https://doi.org/10.1103/PhysRevC.85.034301 ) and Tungsten isotopes (https://doi.org/10.1103/PhysRevC.80.064308 ).

He was the Chair of the PreSPEC International Steering Committee, which oversaw the experimental programme for nuclear structure physics at GSI/FAIR and was an elected member of the NuSTAR Board for the FAIR project in Darmstadt, Germany (2008-2012); Chair of the GSI Users Executive Committee (2009) and the EURISOL User Executive Committee (2012-15).  He was a member of the International Scientific Advisory Committee for the Radioactive Isotope Science Project in Daejeon, South Korea and also currently serves on the Programme Advisory Committee for the Institute of Nuclear Physics Laboratory, in Orsay, Paris, France (from 2013-present). He currently  serves on the Science and Technology Facilities Council (STFC)  Science Board as a non-core member (from 2016-present).

He has served a member of the UK Science and Technologies Facilities Council Education, Training and Careers Committee (2007-2011); Chaired of the South African National Research Foundation Review Committee on Nuclear Physics (2015); and Chaired the Portuguese Research Foundations Committee on Physical and Natural Sciences (2013 and 2016).

He has successfully supervised more than 40 doctoral research students in thesis topics in a range of pure and applied topics, including fundamental nuclear structure physics of the decays of exotic nuclei with equal proton and neutron numbers (https://doi.org/10.1016/S0370-2693(98)00994-0 ; https://doi.org/10.1103/PhysRevLett.81.3337 ; https://doi.org/10.1016/j.physletb.2008.01.017 ); signatures of evolution from vibrational to rotational collective modes in 'transitional nuclei' as a function of increasing angular momentum ( https://doi.org/10.1103/PhysRevLett.90.152502 ; https://doi.org/10.1103/PhysRevC.68.044313 ); the measurement and application of electromagnetic transition rates between nuclear excited states to probe single-particle/collective mode competition and the nature of nuclear deformation( https://doi.org/10.1103/PhysRevC.76.064302 ; https://doi.org/10.1103/PhysRevC.87.014323  ); the origin of high angular momentum states in odd-odd nuclei with limited valence space ( https://doi.org/10.1103/PhysRevC.87.044337 );  nuclear shape evolution ( https://doi.org/10.1103/PhysRevC.95.024328 ); Total absorption decay spectrometry and links to nuclear fission waste decay data ( https://doi.org/10.1103/PhysRevC.96.014320 );  radiation detection system design, modelling and commissioning (https://doi.org/10.1016/j.apradiso.2011.12.023 ; https://doi.org/10.1016/j.radphyschem.2017.02.007 ); radiation dosimetry and radiobiological effects (https://doi.org/10.1016/j.radphyschem.2016.02.030 ); environmental radioactivity measurements ( https://doi.org/10.1016/j.apradiso.2012.04.017); and the provision of radiological and radiopharmaceutical standards and reference materials for environmental source measurements (https://doi.org/10.1016/j.apradiso.2017.02.007 ).

He has also supervised more than 120 MSc research dissertation projects in nuclear and radiation physics.

Paddy was external examiner for MSc and Post-graduate courses at the Universities of Liverpool (2008-2013) and Manchester (2012-2016) and is currently external examiner for the MSc/PgDip course in Nuclear Decommissioning and Waste Management at the University of Birmingham (from 2017-). He has acted as external PhD examiner for 38 doctoral theses, including for universities in Spain (University of Santiago De Compostela); France (Universities of Paris Sud and Bordeaux); Finland (Jyvaskyla); Sweden (U. Stockholm); South Africa (U. of Cape Town); USA (Yale University);  and Germany (University of Cologne); Italy (University of Padova); Canada (Simon Fraser University); and India (Andhra University).

Paddy has been regularly engaged by the TV, radio and written press media on issues related to radiation and nuclear physics. In this capacity he has made over 100 mainstream TV and radio appearances on issues related to radiation physics (see e.g., http://www.bbc.com/news/av/world-asia-pacific-12744973/japan-earthquake-nuclear-physicist-on-radiation-risk ). He has also served as a court-appointed expert witness on the effects of ionising radiation giving evidence on the nature and effects of ionizing radiation from British Nuclear Weapons tests in the 1950 and 1960s (see https://www.judiciary.gov.uk/wp-content/uploads/JCO/Documents/Judgments/ionising-radiation-appeals-20130507+.pdf ).

In his spare time Paddy plays a poor of game golf off an honest 16 handicap and likes to walk Luna, the family dog.

Research interests

Paddy specialises in using gamma-ray and charged-particle spectroscopic techniques to study exotic forms of nuclear matter, with particular emphasis on unusual proton to neutron ratios; the behaviour of nuclei at large angular momentum and the determination of gamma ray transition strengths which can be used to test the best current models of the internal structure of the atomic nucleus. 

This includes work at large scale international accelerator facilities such as GSI-FAIR (Germany) and RIBF-RIKEN (Japan) using secondary radioactive ion-beams produced following high-energy projectile fragmentation and projectile fission reactions to study decays of very exotic nuclear species. These studies focus on  understanding the formation of heavy elements in explosive astrophysical scenarios  (see e.g., https://doi.org/10.1103/PhysRevLett.118.072701 ) and the underlying reasons why some atomic nuclei have non-spherical, prolate deformed shape configurations (see e.g., https://doi.org/10.1016/j.physletb.2016.09.058 ; https://doi.org/10.1103/PhysRevLett.113.262502). 

His expertise is in the design and operation of multi-detection gamma-ray detection spectrometers using both semiconductor (Germanium and Silicon) based  and halide-scintillator (specifically Lanthanum-Tribromide) based materials (see https://doi.org/10.1016/j.nima.2014.02.037 ). Such  spectrometers allow precision measurements of nuclear structure and their characteristic decay properties using gamma-ray coincidence techniques, with their associated digital counting systems routinely able to detect coincident events occurring with less than 1 billionth of a second (i.e. 1 nanosecond) time difference (see e.g.,  https://doi.org/10.1103/PhysRevC.91.027302 ; https://doi.org/10.1103/PhysRevC.87.014323 ). This work has additional potential applications in both medical (radiopharmaceutical) and long-term civilian nuclear waste management quantitative imaging. 

Paddy's research has also overlaps into measurements of naturally occurring radioactive materials (NORM) in environmental samples using applications of the gamma-ray spectroscopic techniques he uses in his more fundamental research projects, including providing radiological maps of the states of Qatar (https://doi.org/10.1016/j.nima.2009.11.029 ), Kuwait  (https://doi.org/10.1016/j.radphyschem.2015.01.041) and coastal regions of Thailand ( https://doi.org/10.1016/j.apradiso.2012.04.017 ; https://doi.org/10.1016/j.jenvrad.2014.07.017 ).

His NPL role includes overseeing the development of novel metrological techniques and instrumentation (https://doi.org/10.1016/j.radphyschem.2017.02.007 ) together with precision measurement of the underpinning nuclear decay data from which primary radiological standards can be produced (https://doi.org/10.1016/j.apradiso.2017.07.056 ). This includes studies related to radiopharmaceuticals and members of the naturally occurring radioactive decay chains (see e.g.,  https://doi.org/10.1016/j.apradiso.2015.04.008 ;   https://doi.org/10.1016/j.apradiso.2015.02.003 ).

Research collaborations

Paddy has led experimental nuclear physics experiments at laboratories in the UK, Denmark, Australia, Canada, South Africa, France, Germany, Italy, Romania, Japan and the USA. He has been the spokesperson for a number of international programmes to produce and study the internal structure of new, radioactive isotopes, including investigations into the variation of nuclear shapes and internal structural competitions as a function of increasing angular momentum or 'spin'.

He is a current co-spokesperson for experiments of the HiSPEC/DESPEC part of the NuSTAR collaboration at the GSI/FAIR facility in Darmstadt and was also co-spokesperson for the NuBALL gamma-ray collaboration based at IPN-Orsay, Paris.
