NoProf. Xuyuan Chen is currently working at Institute of Laser Spectroscopy, Shanxi University, China. He received his Ph.D. in semiconductor materials and devices from the Eindhoven University of Technology, the Netherlands in 1997. After that he jointed Microelectronics Lab at School of Engineering Science, Simon Fraser University, Canada, where he worked on silicon microelectronic device and III-V DFB laser diodes. From 1997, he worked at the Physics Department at the University of Tromso, Norway, as an associate professor, and continued as a professor (2001) until 2002. During that time, his research topics were microelectronic devices and optoelectronics. Dr. Xuyuan Chen joined Microsystems and Nanotechnology, SINTEF ICT, Norway at end of 2002 where he started as a senior research scientist. In 2004, he was appointed as Professor of Department of Microsystems at the University of South-Eastern Norway (previous Vestfold University College). In 2023, he joined Shanxi University. He is currently working on advanced materials and micro-and nano-technoligy, as well as their applications in electrochemical energy storage systems, MEMs, and so on. He is author and co-author of more than 250 scientific publications in international journals and conferences, invited talks, and overview papers in the area of semiconductor technology, micro/nano-systems, and electrochemical technology.
