Dr. Wanfa Wang is an Associate Professor at Guizhou University, affiliated with the Key Laboratory of Karst Georesources and Environment, Ministry of Education. His research focuses on carbon cycling in karst lake‑reservoir systems. Based on typical karst landscapes in Guizhou, he explores regulatory mechanisms of aquatic carbon sinks to support karst ecological conservation and regional dual‑carbon development. He has presided over key research projects including the Youth Program of the National Natural Science Foundation of China and Guizhou Provincial Basic Research Youth Fund (Class B). Over the past five years, as first or corresponding author, he has published 13 SCI papers, including 7 Nature‑Index publications, 12 CAS TOP journal articles and one ESI top‑0.1 % hot paper. He has obtained 5 authorized utility‑model patents (Rank 1). He established Guizhou’s first offline vacuum pretreatment platform adopting wet‑ and dry‑oxidation for stable and radiocarbon isotopes of diverse carbon fractions, with two relevant utility‑model patents granted. This platform supports carbon‑source tracing and internal carbon‑sink estimation for karst lake‑reservoir systems. In student training, he has supervised undergraduates to obtain one national‑level and two provincial‑level innovation training programs. His undergraduate and postgraduate students have won the national third‑class award and provincial first‑ and second‑class awards in discipline competitions. He serves as Youth Edit
