Jiajia Liu received his B.S. and M.S. degrees both in computer science from Harbin Institute of Technology in 2004 and from Xidian University in 2009, respectively, and received his Ph.D. degree in information sciences from Tohoku University in 2012. He was a JSPS special research fellow in Tohoku University from Apr. 2012 to Oct. 2013, and a data analytics engineer in Aviation Industry Corporation of China from Jul. 2004 to Aug. 2006. He has been a Full Professor at the School of Cyber Engineering, Xidian University, since 2013, and has been selected into the prestigious “Huashan Scholars” program by Xidian University since 2015. He has published more than 50 peer-reviewed papers in many high quality publications, including prestigious IEEE journals and conferences. He has received the Best Paper Awards from many international conferences including IEEE flagship events, such as IEEE WCNC in 2012 and 2014. He was the recipient of the prestigious 2012 Niwa Yasujiro Outstanding Paper Award due to his exceptional contribution to the analytics modeling of two-hop ad hoc mobile networks, which has been regarded by the award committees as the theoretical foundation for analytical evaluation techniques of future ad hoc mobile networks. He was also a recipient of the Tohoku University President Award 2013, Graduate School of Information Sciences Dean Award 2013, Professor Genkuro Fujino Award 2012, Chinese Government Award for Outstanding Ph.D. Students Abroad 2011 and the RIEC Student Award 2012. His research interests cover a wide range of areas including load balancing, wireless and mobile ad hoc networks, Fiber-Wireless networks, Internet of things, network security, LTE-A and 5G, SDN and NFV. He has been actively joining the society activities, like serving as associate editor for IEEE Transactions on Computers (Oct. 2015-present), the editor for IEEE Network (July 2015-present), guest editors of top ranking international journals like IEEE Transactions on Emerging Topics in Computing (TETC), IEEE Internet of Things (IoT) Journal, etc., and serving as technical program committees of numerous international conferences. He is a senior member of IEEE.
