Kai-Qiang Lin serves as Professor in the Department of Chemistry at Xiamen University's College of Chemistry and Chemical Engineering since 2023, following academic appointments at Germany's University of Regensburg (2018-2022). His research laboratory operates from Tan Kah Kee Innovation Laboratory Building (Room 2313). Academic Background: B.S. in Chemistry, Xiamen University (2009-2013) Ph.D. in Physical Chemistry, Xiamen University (2013-2018) Postdoctoral Researcher, University of Regensburg (2018-2019) Akademischer Rat a.Z., University of Regensburg (2020-2022) Research Focus: Dr. Lin pioneers experimental investigations of quantum optical phenomena in two-dimensional materials, specializing in ultrafast spectroscopy of excitonic systems. His work bridges quantum nonlinear optics and optoelectronics , with emphasis on valley-polarized trions, interlayer excitons, and twist-angle engineered heterostructures in transition metal dichalcogenides like WSe 2 . This research enables breakthroughs in quantum information processing and nanoscale optoelectronic devices. Publication Trends: His 9 recent papers (2017-2024) in Nature-family journals demonstrate consistent leadership in 2D material photonics , evolving from plasmonic sensing (2017) to ultraviolet excitonics (2024). Key thematic progression shows increasing focus on quantum interference effects and moiré superlattice engineering for controlling light-matter interactions at sub-nanometer scales. Scientific Recognition: Walter-Schottky-Preis (2023) Invited to 69th Nobel Laureate Meeting, Lindau (2019) Laboratory Operations: The LKQ Lab (lkqlab.xmu.edu.cn) maintains experimental facilities for ultrafast laser spectroscopy and low-temperature optical characterization, directing research on quantum optical phenomena in van der Waals heterostructures through international collaborations with groups in Germany, Japan, and the US.
