Yong Chen received his B.S. degree in physics from Wuhan University in 1982, M.S. and Ph.D. from University of Montpellier in 1983 and 1986, respectively. Next, he spent three years in Scuola Normale Superioriedi Pisa and Peking University, as a Research Associate. In 1990, he joined the Centre National de RechercheScientifique (CNRS) as Chargé de Recherche (1st class) and became Directeur de Recherche (2nd class) in 1998. Finally, he moved to the Ecole Normale Supérieure (ENS) of Paris as Professor in 2003 to build his current laboratory for interdisciplinary studies. He is now Directeur de Recherche (1st class) of CNRS, Adjunct Professor at the Institute of Integrated Cell-Material Sciences (iCeMS) of Kyoto University, Changjiang Scholar (lecture) at Peking University and Distinguished Chair Professor at Hong-Kong Polytechnic University. During more than 25 years, he has been worked in different fields of nanosciences and nanotechnologies, including semiconductor quantum heterostructures, photonic crystals, scanning near field optical microscopy, magnetic nanostructures,synchrotron based X-ray lithography, thermal and UV nanoimprint lithography, etc. During the last ten years, he was mainly interested in microfluidics and its application in molecule and cell biology. He has authored or co-authored more than 400 scientific publications, in which more than 300 were in peer-reviewed journals (ISI web of science) and 10 as book chapters. He has also contributed to a large number of European contracted research projects/networks and national projects. Finally, he has supervised more than 40 Ph.D and post-doctoral studies in interdisciplinary research areas.
