Stefanos Paschalis

Stefanos Paschalis is a Senior Lecturer in the School of Physics, Engineering and Technology at the University of York, UK. He holds a Ph.D. from the University of Liverpool. His research focuses on ionizing radiation detection technology and the study of exotic nuclei to explore nuclear structure and the strong nuclear force. Key projects include detector development for societal applications and fundamental physics experiments.

He has led initiatives such as

• Position reconstruction in scintillators (STFC-funded, 2017–2019)
• Neutron/gamma discrimination for nuclear security (2017–2020)
• Digital SPAD arrays for radiation detectors (EPSRC-funded, 2017)

Research interests include quasifree scattering reactions, neutron-rich nuclei, and radiation detector innovation. His work bridges fundamental physics (nuclear structure) and applied fields (medical imaging, security systems). He has advised six PhD students and contributed to over 130 publications.

Teaching responsibilities include Year 3 Frontiers of Research, Year 2 Nuclear Physics, and Year 1 Professional Skills modules. He also serves as a Year 1 Tutor and Graduate Admissions Tutor.

Grants and collaborations span international institutions like Lawrence Berkeley National Lab and CERN, focusing on FAIR R3B experiments and exotic nuclei studies. His lab work emphasizes precision measurements and detector technology advancements.
