RESUME

Dr. Pengcheng Xu received his B.S. degree from Zhengzhou Institute of Light Industry, M.S. degree from Shanghai University and Ph. D. degree from University of Chinese Academy of Sciences. Now he is an associate professor at the State Key Laboratory of Transducer Technology, Shanghai Institute of Microsystem and Information Technology, Chinese Academy of Sciences. His recent research covers advanced sensing materials (like nanowires, hyperbranched polymers and nanoporous materials), micro/nanofluidic chips and MEMS/NEMS-based chemical sensors. More recently, Dr. Xu and co-workers opens up a new route to quantitatively extract the thermodynamic/kinetic parameters of various kinds of advanced functional materials, based on the micro-gravimetric platform of resonant microcantilevers. Dr. Xu is a member of the Chinese Special Committee of Gas and Humidity Sensor Technology. He has over 80 peer reviewed publications with a Google Scholar H-Index >18. He holds over 20 Chinese patents. He also served as a referee for numerous journals, such as Sensors and Actuators B.
