Born in 1968, Lionel Vayssieres obtained a MSc. in physical chemistry (1990) and a Ph.D. in chemistry (1995) from the University Pierre & Marie Curie, Paris, France for his research on the interfacial thermodynamic growth control of metal oxide nanoparticles in aqueous solutions. Thereafter, he joined Uppsala University, Sweden as a researcher where he pioneered nanorod-based oxide structures for photoelectrochemical applications. He was a visiting scientist at University of Texas at Austin; UNESCO Centre for Macromolecules & Materials, Stellenbosch University, and iThemba LABS, South Africa; Lawrence Berkeley National Laboratory; Texas Materials Institute; Ecole Polytechnique University de Lausanne, Switzerland; University of Queensland, Australia, and Nanyang Technological University, Singapore as well as an independent scientist at the National Institute for Materials Science, Japan for eight years working on quantum-confined oxide nanodevices. Since 2012, he is a full time 1,000-talent scholar professor, co-founder and co-director of the International Research Center for Renewable Energy at Xan Jiaotong University, China. He's also, since 2003, the founding editor-in-chief of theInternational Journal of Nanotechnologyand a guest scientist at Lawrence Berkeley National Laboratory. He has published 100+ publications which have generated over 7,700 citations since the year 2000 including highly cited papers in materials science, chemistry, physics, and environment fields and presented over 320 lectures in 28 countries.
