Rate My Professor Paul Sellin

Professor Paul Sellin is a Professor of Physics at the University of Surrey, within the School of Mathematics and Physics in the Faculty of Engineering and Physical Sciences. He obtained his BSc in Physics (Hons., First Class) from the University of Birmingham in 1988 and his PhD in Experimental Nuclear Physics from the University of Edinburgh in 1992, with a thesis on proton radioactivity measurements using a double-sided silicon strip detector. Sellin served as Head of the Department of Physics at the University of Surrey from 2010 to 2015. He holds visiting professor appointments at the Department of Medical Physics and Biomedical Engineering at University College London and the Department of Physics at the University of Wollongong, Australia. His career has focused on advancing detector technologies, contributing to fields such as nuclear physics, medical imaging, and security applications.

Sellin's research specializations include the development and characterisation of radiation detectors and detector materials, encompassing perovskite radiation detectors, plastic and organic scintillators for neutron/gamma detection, radiation-hard materials for high-dose environments, and applications in nuclear security science. He is recognised as a Fellow of the Institute of Physics (FInstP), Chartered Physicist (CPhys), and Member of the Institute of Electrical and Electronics Engineers (MIEEE). Notable publications include 'Towards superior X-ray detection performance of two-dimensional halide perovskite crystals by adjusting the anisotropic transport behavior' (Journal of Materials Chemistry A, 2021), 'Scintillation Properties of CsCu2I3 Perovskite Single Crystal Grown by Room Temperature Solution Processing Method' (IEEE Transactions on Nuclear Science, 2025), 'Perovskite X-ray Detectors' (Perovskite Optoelectronic Devices, 2024), and 'Organic Spacers modulated low dose X-ray detection in hybrid halide 2D perovskites' (Small, 2025). Sellin leads the largest UK research team on perovskite materials for radiation detection and is involved in national programmes training the UK's nuclear workforce, enhancing detector technologies for hazardous material identification and space applications.
