Zhigang Lei was born in Hubei province (China) in 1973. He received his B.S. degree in 1995 from Wuhan Institute of Technology, and Ph.D. degree in 2000 from Tsinghua University. Then, he became a postdoctoral researcher in Beijing University of Chemical Technology working with Professor Chengyue Li. In 2003 - 2005, he worked as a researcher in Research Center of Supercritical Fluid Technology (Tohoku University, Sendai, Japan). In 2005 - 2006, he got the world-famous Humboldt Fellowship and carried out his research in Chair of Separation Science and Technology (Universität Erlange-Nürnberg, Erlangen, Germany). In 2006, he came back to China. He is now a Professor in State Key Laboratory of Chemical Resource Engineering (BUCT, China). His current research interests include chemical process intensification and predictive molecular thermodynamics. He has contributed to about 140 papers in international journals and one book entitled "Special Distillation Processes published by Elsevier B.V. (2005).
