Wang Xinchu is an Associate Research Professor at the School of Earth System Science, Tianjin University. His research focuses on clumped isotope geochemistry and global change. He received his Ph.D. in Environmental Science from the School of Earth System Science, Tianjin University, in 2024 under the supervision of Academician Cong-Qiang Liu. From 2023 to 2024, he conducted collaborative research in the Division of Geological and Planetary Sciences at the California Institute of Technology, with Professor John M. Eiler as his host supervisor.

His research has long focused on methodological innovation in isotope geochemistry and its applications to carbon cycling in the surface Earth system. He pioneered the development and application of high-resolution mass spectrometric methods for methane clumped isotope analysis in China. By integrating isotope measurements with machine learning, big data analysis, and process-based modeling, his work investigates methane sources, transformation processes, and feedback mechanisms under global change in aquatic environments, wetlands, coalbed methane systems, and other Earth surface settings.

He has led several research projects, including the Young Scientists Fund Category C of the National Natural Science Foundation of China, the National Postdoctoral Researcher Program, the China Postdoctoral Science Foundation–Tianjin Joint Fund, the General Program of the China Postdoctoral Science Foundation, and the Tianjin Postdoctoral Innovation Position Program. He has also participated in major National Natural Science Foundation of China projects, including “Response and Adaptation Mechanisms of Peatland Carbon Pools to Global Change” and “Structure, Processes, and Ecosystem Services of the Coastal Critical Zone around the Bohai Sea.”

He has published extensively in leading international and domestic journals. As an independent first author or sole corresponding author, he has published 10 papers in journals including *Environmental Science & Technology*, *Earth and Planetary Science Letters*, *Earth-Science Reviews*, *Water Research*, *Journal of Hydrology*, and *Journal of Analytical Atomic Spectrometry*. His representative contributions include the development of high-resolution mass spectrometric methods, the identification of thermogenic and secondary microbial methane, the investigation of methane cycling in aquatic systems, and isotope-based constraints on the global methane budget and related biogeochemical processes. These studies have advanced methane clumped isotope geochemistry from methodological development toward broader applications in environmental tracing and global change research.

He has delivered oral presentations at major international and domestic conferences, including the AGU Fall Meeting, the Geological Society of America Annual Meeting, and the Asia Oceania Geosciences Society Annual Meeting. He has also served as a convener for academic sessions such as “Clumped Isotope Geochemistry: Methodological Innovation, Fractionation Mechanisms, and Frontier Applications” at the National Conference on Gas Isotope Geochemistry, as well as related sessions at The Innovation Conference on Geoscience. He was selected for the National Postdoctoral Program for Innovative Talents and the Tianjin Postdoctoral Innovation Position Program. During his doctoral training, he received several honors, including the Outstanding Doctoral Dissertation of Tianjin Municipality, Outstanding Student of Tianjin Municipality, National Scholarship for Doctoral Students, and the Tianjin University Excellent Doctoral Dissertation Cultivation Fund. He currently serves as a young editorial board member of *Chinese Journal of Applied Ecology* and *Chinese Journal of Ecology*, and has long served as a reviewer for international journals including *Geochimica et Cosmochimica Acta*, *Water Resources Research*, and *Organic Geochemistry*.

Undergraduate and graduate students interested in isotope geochemistry, instrumental techniques and analytical method development, carbon cycling in the surface Earth system involving water, soil, atmosphere, and biology, as well as environmental applications of big data and machine learning, are welcome to join the research team. Students with interdisciplinary backgrounds in GIS and remote sensing, microbiology, and related fields are also encouraged to apply.
