Dr. Ling Pei (born 1977.09) has been an associate professor in the School of Electronics, Information and Electrical Engineering at the Shanghai Jiao Tong University (SJTU), China since 2013. He has authored or co-authored over 50 scientific papers. He is also an inventor of 6 patents and pending patents. From 2007 to 2013, he worked as a specialist research scientist at Finnish Geodetic Institute in Finland. His research interests include indoor/outdoor seamless positioning, ubiquitous computing, wireless positioning, mobile computing, context-aware applications and location-based services. He has been involved in multiple EU, ESA (European Space Agency), Finnish Academy and TEKES (the Finnish Funding Agency for Technology and Innovation) projects. Most of his research activities are cooperated with some Finnish international companies, e.g. Nokia, Fastrax, Bluegiga, and Ekahau. Furthermore, he was a research analyst candidate of Apple iOS Wireless Team in US headquarter. The excellence research work Dr. Pei involved has been recognized to the public via e.g. a cover story in the most popular navigation magazine "GPS World" twice (Feb. Issue 2010, and Oct. Issue 2012) and a part of a feature story in the Finnish National TV. Nowadays, he has been an advisory committee and technical program committee member of the International Conference on Advances in Satellite and Space Communications. Moreover, he is an editorial board member of the International Journal of Advanced Robotic Systems Editorial Board, and the International Journal On Advances in Telecommunication a paper reviewer for IEEE Pervasive Computing magazine, Sensors, International Journal of Geographical Information Science, Journal of Navigation, and various IEEE international conferences.
