Researcher biography

Dr Xiao Guo is a Postdoctoral Research Fellow at The University of Queensland. He received his PhD from UQ in 2022. His research focuses on scanning near-field optical microscopy (s-SNOM) and light–matter interactions in nanomaterials and nanostructures across the mid-infrared to terahertz spectrum. Since 2022, he has completed 50+ independent peer reviews for internationally recognised journals, including Nature Communications, Light: Science & Applications, and ACS Photonics. He lectures ELEC3100: Fundamentals of Electromagnetic Fields and Waves at UQ. He has delivered invited talks at NFO-17 and a 50-minute invited seminar at IRMMW-THz 2024.

His community service includes interim session chair (THz) at ISUPTW 2024 (IEEE Photonics Society), Technical Program Committee member for the 4th and 5th International Conference on Advanced Optics & Photonics Research in Engineering, Youth Editorial Board member of PhotoniX Life (companion to PhotoniX, IF 19), and external grant reviewer for a European funder. His invited review on terahertz near-field optical microscopy in Applied Physics Reviews was recognised as an ESI Highly Cited Paper (top 1%) in 2024 and 2025. He is a member of the Institute of Physics (IOP), the American Chemical Society (ACS), and the Australian Institute of Physics (AIP).
