Prof. Li Liu obtained her bachelor’s degree from Nankai University in 1998 and completed her Ph.D. at Shanghai Institute of Organic Chemistry, CAS, in 2003. After postdoctoral research on nanotechnology in Portland State University (USA) and supramolecular chemistry in University of Cambridge (UK), she joined Dalian Institute of Chemical Physics, CAS, as an associate professor and DICP-100-talents in 2008. She moved to Dalian University of Technology in 2013, and since 2021, she was promoted to professor at Inner Mongolia University supported by Program of Higher-level Talents. Her research interests include biomass utilization, ionic liquids, supramolecular chemistry and nanotechnology. She has published 30+ papers on high impact factor journals along with eight patents.
