Xiaodong Yang is a Professor, Associate Professor of Key Laboratory of Medicinal Chemistry for Natural Resource, Ministry of Education, Yunnan University. Yunnan is well-known for its sufficient natural resources particularly biological and mineral resources. Our discipline has recently performed studies and developed technologies, taking advantage of the active ingredients from biologically natural products and the rare and noble metals from minerals, on organic chemistry using biological resources, separation, and analytical chemistry in low grade or used rare and noble metals, waste-water treatment via catalytic degradation and chemical processes. The department focuses on fundamental and cutting-edge research in many aspects of chemistry in order to propose solutions to the sustainable and environmentally friendly development of the nation and regions. With the hard-working and accumulation of faculty members for decades, our discipline has comprised five competitive and characteristic research areas, i.e., organic synthesis, functionalized materials and catalysis, separation-analysis-utilization of rare and noble metals, and natural products and pharmaceuticals, and computational chemistry.
