Tuan Guo, is a researcher, doctoral supervisor, winner of the National Excellent Youth Science Foundation, the first batch of special support projects in Guangdong Province, "top-notch young talents in science and technology innovation", and the first batch of "Pearl River Science and Technology Nova" in Guangzhou. In 2007, he received his Ph.D. from the Institute of Modern Optics of Nankai University, and from 2007 to 2010, he was engaged in postdoctoral research at the University of Carlton in Canada and the Hong Kong Polytechnic University.

The main research fields are advanced photonic devices, optical fiber sensing, biphotonic and energy photonics. He presided over more than ten research projects at the national and provincial levels, including the National Excellent Youth Fund Project, the Guangdong Natural Fund Key Project, and the Guangzhou University-Industry Research Cooperative Innovation Major Special Project. In Nature Communications, Light: Science & Applications (Cover Papers), Biosensors and Bioelectronics, Analytical Chemistry and other authoritative journals published more than 90 SCI papers, and was invited to Analytical and Bioanalytical Chemistry, Journal of Lightwave Technology, Journal of Selected Topics in Quantum Electronics. Authoritative journals such as Nics have written 6 invited review papers, selected 2 highly cited Web of Science papers, citing more than 2300 times (h index 22), participated in Springer Nature's book Handbook of Optical Fibers, and made more than 30 invited reports at international conferences, and applied for 19 national invention patents (7 authorizations) as the first inventor. One international TCP patent and one international TCP patent. The research results were specially reported by the authoritative optical review journals Nature Photonics, Optics & Photonics News and Laser Focus World. The self-developed fiber-optic vector vibration and vector torsion sensor is applied to the "comprehensive monitoring and early warning system of power grid disasters" in the Southern China Power Grid, which provides real-time remote monitoring for live transmission lines, predicts hidden dangers of transmission equipment and improves the monitoring capability of power system. It has been highly appraised by the Southern Power Grid Company.

Co-Chairman of Photonic Technology in Instrumentation and Measurement Technical Committee of International IEEE Instrument and Measurement Association, Chairman of OSA CLEO-PR of International Conference and Branch of IEEE I2MTC Technical Committee. He has served as the vice-editor/guest editor-in-chief of the international authoritative journal IEEE/OSA Journal of Lightwave Technology, MDPI Sensors, senior member of the International IEEE Association (IESenior Member), senior member of the American OSA Association (OSA Senior Member), and member of the Photoelectric Technology Committee of the Chinese Optical Society.
