Prof. Dr. Wen-Hua Sun heads a group of organometallic chemistry and catalysis at the Institute of Chemistry Chinese Academy of Sciences since October of 1999, nowadays has also been a professor teaching at the University of Chinese Academy of Sciences from 2014. Received his B.Sc. in chemistry at Lanzhou University (1986) and Ph.D at Lanzhou Institute of Chemical Physics (LICP, 1989/1994). He worked in LICP as Associate Professor (1993) and Hokkaido University with JSPS, COE and JST. He was visiting professors at Munster University (2001-2002), Nagoya University (2003), Louis Pasteur University (2005) and Strasburg University (2009). He was selected as Fellow of Royal Society of Chemistry (2011) and member of European Academy of Sciences (2017). His contributions have had international impacts across the areas of polymerization catalysts for conversional alpha-olefins and polyolefins, biodegradable polymers and bio-massive process as well as their intermediates and reaction mechanism. One of their iron catalysts is efficiently operated in ethylene oligomerization for alpha-olefins in SinoPec. His group has been opened to domestic and international colleagues, those collaborations have visually recognized according his publications indicating coauthor members from various affiliations. His services in academy include editorial board members for Polymer, Royal Society Open Science, Molecules, Catalysts, Polyolefin Journal, Inorganics and General Chemistry currently.
