Dr. Weichun Yang received her B.E. degree in Instrumentation Science and Engineering from Huazhong Agricultural University, Wuhan, Hubei, China, in 2004, and the Ph.D. degree in Environmental Science from Nankai University, Tianjin, China, in 2009. Dr. Yang has worked in the School of Metallurgy and Environment of Central South University in 2009 and became a professor since 2017. Dr. Yang focuses on the research of remediation of heavy metal-contaminated soil. Her recent research interests include: ecological restoration of mining area, interaction of minerals and microbe, heavy metal-contaminated soil remediation materials, etc. Dr. Yang has published 76 peer-reviewed technical papers in international journals and conferences and two monographs, "Treatment and Ecological Restoration of Mining and Metallurgical Contaminated Sites" and "Theory and Technology of Microbial Treatment of Chromium Pollution." Dr. Yang authorized 92 national invention patents (23 first inventors).



Dr. Liyuan Chai is the director of the National Engineering Technology Research Center for Heavy Metal Pollution Prevention and Control. He is the professor at Central South University and the academician of the Chinese Academy of Engineering. Professor Liyuan Chai has devoted himself to the research in the field of non-ferrous metallurgy environmental engineering for decades. He invented a number of non-ferrous smelting pollution control and recycling technologies, such as clean metallurgy of arsenic-containing polymetallic materials, recycling of smelting waste acid, purification and reuse of heavy metal wastewater. These accomplishments have achieved large-scale promotion and application and promoted the industrial transformation, upgrading and green development of non-ferrous industry. He has won 2 second prizes of National Technological Invention Award, 1 second prize of National Science and Technology Progress Award, 8 first prizes of provincial and ministerial level
