Yan Xu is an Associate Professor (tenured) and the principal investigator of the Nanofluidics Lab at Osaka Prefecture University, Japan. He received his bachelor’s degree (2001) from Dalian University of Technology and his master’s degree (2004) from Dalian Institute of Chemical Physics, Chinese Academy of Sciences. He completed his Ph.D. (2007) at the University of Tokyo. Research in his group is directed toward the use of nanofluidic devices for chemistry, biology, and materials science at femtoliter, attoliter, and single molecule scales. His research group continues to involve the study and development of novel nanofluidic methods for single cell omics, single molecule chemistry, biomaterials, and nanomedicine. He has recently (co-) authored over 60 micro-/nanofluidics-related papers in Adv. Mater., Small, Biomaterials, ACS Appl. Mater. Interfaces, Lab Chip, etc., with seven papers featured on the covers of the journals. He has been invited to write reviews for Adv. Mater. and other top journals. He has also delivered many invited talks (eg., 40+ after 2015) and received several awards from Japan, USA, and China.
