Dr. Xuesong Li is the inventor of the method of synthesis of large-area graphene films on Cu foils by chemical vapor deposition of methane. He got his B.S. and M.S. from Tsinghua University in 2000 and 2003, respectively and his Ph.D. from Rensselaer Polytechnic Institute in US in 2007. From May 2007 to Jan. 2012 Dr. Li pursued his post doctorate research in UT Austin and IBM T. J. Watson Research Center, respectively. In Feb. 2012, Dr. Li, together with his colleagues, co-founded Bluestone Global Tech, a company on graphene commercialization, and then LasLumin LLC in Jun. 2014. Dr. Li was awarded the 11th China 1000-talent plan (young-talent) and joined University of Electronic Science and Technology of China in 2015 as a professor. Dr. Li’s research interests are synthesis and applications of carbon nanomaterials such as carbon nanotubes and graphene. He has published 47 papers in peer reviewed journals such as Science, Nature Nanotechnology, Nature Materials, Nature Photonics, etc. with total citations over 14000, including 14 ESI highly-cited papers. His research work has been widely reported by multi-media such as BBC news, Nature, ScienceDaily, C&EN, etc.  His work on graphene synthesis by chemical vapor deposition of methane on copper foil substrate, which was published in Science in 2009, was selected as one of the breakthroughs in 2009 by Science and has been cited close to 5000 times. This invention has been widely used in both academy and industry up to date for graphene film production.
