Dr. Chiu Wee Siong is currently a senior lecturer at Department of Physics in University Malaya. He received both of his Bachelor of Science (Nuclear Science) and Master of Science (major in Materials Science) in UKM. Thereafter, he enrolled his Ph.D. degree in Chemical Engineering at University of Nottingham. His research interests cover the aspects of synthesis and characterization of solid-state nanostructural materials, which consisted of oxide- and 2D-based semiconductor and magnetic-nanomaterials, graphene nanocomposite, novel metal nanoparticles as well as photocatalyst nanocomposite. His current research work mainly focuses on the design of value-added nanostructural photocatalyst materials for photoelectrochemical application in producing hydrogen gas through water splitting reaction. He has published 95 papers in ISI-cited peer-reviewed journals and 30 conference proceedings. He has earned 2505 citations with total H-index of 26 according to ISI-Web of Science. Up to date, he has led 7 external grants and 6 internal grants with the sum of ~2-million and successfully filed two patents. Furthermore, he has received Young Scientist Award from Malaysia Association for Solid State Science and Technology. For the number of postgraduate students, he has successfully produced 10 PhD students and 2 master students. Moreover, he is actively involved in social engagement activity inclusive of serving as auditor/reviewer for numerous of well-known international fundings cum renowned publishers. His dedication in research also has honoured him with 17 awards both internationally and locally. In the meantime, he is also honoured with “Trusted Reviewer by UK Institute of Physics” in addition to the honour of Recognized Reviewer Award for numerous of ISI-cited journals under Elsevier Publisher. Furthermore, he has being appointed as Scientific Coach by Ministry of Science, Technology and Innovation (MOSTI) for International Nanotechnology Olympiad (INO) and won gold medal with the honour of Best Project in Science and Technology Development. In the meantime, he also has won gold medal for the Green Hydrogen Technology Invention in International Materials Invention Competition in Nov 2024. With respect to his expertise in nanoscale materials for hydrogen production, lately, he has been elected as Guest Editor for a journal (Discover Nano) under Springer Nature, in managing publications associated to the “Green Hydrogen Production via Nanoengineering Approach”. On the other hand, his well-recognized expertise in semiconductor physics and photoelectrochemistry also renders him to be invited as plenary speaker and invited speaker in both international- and local-conferences. In terms of teaching, he has reflected multi-tasking and can diversify his teaching philosophy to wide range of subjects that ranges from materials physics to modern physics. Meanwhile, he has been appointed as external assessor for Curriculum Review of Materials Science Program in UiTM Shah Alam and serve as judge for numerous of scientific competitions. Finally, he has actively contributed to faculty administration task by serving as Quality Manager in handling auditing task, troubleshooting quality issues and managing special task force for the well-being of department and faculty. Additionally, his excellence contribution to department has rendered him to be awarded with excellent service certificate thrice.
