Sang Soon Oh

Dr. Sang Soon Oh is a Lecturer at the School of Physics and Astronomy, Cardiff University, and a Sêr Cymru II Rising Star Fellow (2017-2023) funded by the Welsh government. His research spans theoretical and experimental aspects of topological photonics, photonic crystals, semiconductor lasers, and chiral metamaterials, with a focus on graphene-based systems and quantum emitters.

• Education: PhD in Physics from KAIST (2007), with a research visit at the University of St Andrews (2004-2005).
• Postdoctoral: ETRI (2007-2010), University of Surrey (2010), Imperial College London (2010-2017).

His research interests center on:

• Topological protection mechanisms in photonic systems
• Non-Hermitian and non-linear photonic dynamics
• Quantum dot and nanowire laser integration
• Chiral and plasmonic light-matter interactions

Selected publication trends reveal:

• Advances in nonlinear topological photonics (2025)
• Non-Abelian nodal line physics in photonic and mechanical systems (2024-2022)
• Graphene plasmonics and 2D material applications (2024)
• Machine learning for topological phase diagram analysis (2023)

Scientific recognition:

• Sêr Cymru II Rising Star Fellowship (£983K)
• Outstanding reviewer for Light: Science & Applications (2022, 2023)

Supervision includes:

• Current PhD students: Ghada Alharbi (optical bistability), Kyle Netherwood (quantum filtering), Ion Wood-Thanan (aperiodic materials)
• Former PhD students: Stephan Wong (topological lasing), Zeeshan Ahmad (graphene plasmonics), Joe Mahoney (quantum dot modulators), Shaikhah Almousa (resonator theory)
• Collaborative supervision of Jan Olthaus (Münster University) and 3 external PhD examining roles
