Oscar Carl Olof Dahlsten is an Associate Professor in the Department of Physics at City University of Hong Kong. He works in the field of quantum information science with research spanning information thermodynamics, foundations of quantum theory, and quantum computation and machine learning. His academic journey includes training at Imperial College and previous positions at ETH Zurich, NUS Singapore, Oxford University, and SUSTech before joining CityUHK. Dahlsten's research interests focus on the intersection of quantum mechanics and information theory. His work explores how quantum systems process information, the thermodynamic implications of quantum operations, and the application of quantum principles to computational problems. Key areas include quantum causal inference, quantum energy harvesting, black hole information theory, and quantum machine learning algorithms. His fingerprint analysis shows strong contributions to Quantum Theory (100%), Statistical Mechanics (55%), Quantum Dot physics (55%), and Free Energy concepts (40%). Recent publications demonstrate a strong trend toward experimental validation of quantum information concepts, particularly in quantum causal inference and quantum thermodynamics. His work bridges theoretical foundations with practical applications, especially in energy harvesting and quantum computing. The integration of quantum principles with thermodynamic laws appears as a consistent theme across his recent publications. Dahlsten currently serves as Principal Investigator for the GRF project 'Exploiting Quantum Systems for More Efficient Extraction of Energy From Random Sources' starting September 1, 2025. He actively supervises PhD students in quantum information science and is accepting new PhD candidates. His research group focuses on cutting-edge problems at the intersection of quantum information, thermodynamics, and computation.

Jason Chun Shing Pun is a Senior Lecturer in the Department of Physics at the University of Hong Kong, focusing on light pollution research and public science education. He has contributed to astrophysics, neutrino physics, and cosmic ray studies while leading environmental outreach initiatives. Education: B.A., B.S. (Rochester), M.A., Ph.D. (Harvard) Key Research Areas: Light pollution monitoring, supernova remnants, neutrino experiments, and X-ray sources in galaxies His work spans astrophysics and environmental science, with notable projects like the Daya Bay neutrino experiment and Aberdeen Tunnel cosmic ray research. He also initiated Hong Kong's night sky brightness monitoring network. Recent publications emphasize urban light pollution analysis via satellite data (VIIRS, Luojia-1), Earth Hour natural experiments, and multi-source methods. These studies highlight trends in artificial lighting, urban planning, and citizen science engagement. Scientific accolades include the 2022 Secretary of Home Affairs’ Commendation Scheme and the 2018 Dark Sky Defender Award. He has secured grants from the HKSAR Environment and Conservation Fund and HKU Teaching Development Grant. Dr. Pun actively engages in public education through workshops, competitions, and collaborations with international bodies like the International Astronomical Union. His projects, such as the GaN-MN YouTube channel and bilingual education booklets, demonstrate a commitment to global light pollution awareness.
