Dr. Siliang Li is Professor and the excellent young scientist funded at 2015 by National Natural Scientific Foundation of China (NSFC). His study is mainly focused on environmental geochemistry, estimation of nitrate sources and transformation based on stable isotopes, chemical weathering processes in the rivers, biogeochemical processes and C-S-N coupling in karst critical zone. His oversea working experiences include being a visiting scholar in Department of Earth Sciences in University of Cambridge, UK, IPGP and Ecole Normale Supérieure de Lyon in France. He has carried out over 10 research projects on biogeochemistry and nutrient cycling. He has published over 50 peer-reviewed journal papers and proceedings, among which over 30 are in the international journals (e.g. EPSL, EST, Chem Geol). He is also the reviewer for multiple high-quality journals e.g. EST, GCA, WR, Chem Geol, J Hydrol.
