I am now working at the School of Metallurgy and Environment, Central South University (CSU) in China. CSU has strong background in metallic material and metallurgy. The school has established a separation and purification platform that focuses on the research in membrane-based separation for hydrometallurgy processes and a center for wastewater treatment specifically addressing heavy metals. In recent years, many good ideas and publications about membrane application in metallurgy and heavy metal waste treatment have been delivered by the researchers in the school. I am a key member of the platform and the center. My current and upcoming research effort is concentrated on 1) membrane preparation and optimization for Forward Osmosis, Nanofiltration, Pervaporation and Membrane distillation, and 2) membrane applications for the green development metallurgical process. Before came to CSU, I worked as a (Senior) Research Fellow from 2005 to 2009 at the Nanoscience and Nanotechnology Initiative (NNI) of National University of Singapore (NUS), and carried out research in “Sub-nano Pore Size Membranes for Biofuel Separation and Purification” and “The Development of Mixed Matrix Nano-composite Materials for Membrane Separation”. From 2002 to 2005, I was awarded the research scholarship to pursue my doctoral studies on “Membrane Formation and Characterization for Gas Separation” at the Department of Chemical and Biomolecular Engineering of NUS. I got my PhD in 2006. I received my B.Sc. degree (1997) from the Department of Environmental Science, Wuhan University, China. As 1st and major inventor, I have applied 3 US patents, 1 Singapore patent and 9 China patents, 3 of them have been authorized. 22 papers have been published in Journal of Membrane Science, Chemical Engineering Science, Carbon, Progress in Polymer Science etc. I have given more than 20 oral presentations at international meetings or conferences related to membrane separation and material science. Li Na is a Vice-Professor at Nanjing Normal University of China. She works at the Jiangsu Key Laboratory of 3D Printing Equipment and Manufacturing of China. She has published 10 papers and 1 book, and holds 3 patents about 3D printing technology in China.
