Prof. Yi Cheng received his B.E. and Ph.D. degrees in Chemical Engineering from Tsinghua University in 1994 and 2000. He worked as a research fellow at Delft University of Technology (11/1998-11/2000), and then as a postdoc research associate at University of Western Ontario (02/2001-03/2003). In March 2003, he joined Tsinghua University as an associate professor, and was promoted as a full professor in December 2007. His research interests lie in the field of multiphase reactor engineering in relation to the applications for energy, environment and materials. In the early period, major efforts were made to understand the hydrodynamics and nonlinear dynamics in various fluidized beds by experimental techniques and mathematical modeling. In recent years, he has extended his research activities tremendously, that is, using unconventional means of process intensification (i.e., plasmas and confined micro-channel or micro-droplets) to solve reaction engineering problems. He has authored or coauthored about 180 journal articles, 40 patents, 1 book and 2 book chapters. He has received several awards such as the first prize of Natural Science Award by the Ministry of Education of China (2013) and the first prize of Science and Technology Progress Award by China Petroleum and Chemical Industry Federation (2014).
