Nan Xie received his B.S. degree in communication engineering and M.S. degree in circuits and systems, both from Wuhan University, Wuhan, China, in 2003 and 2006, respectively. From 2006 to 2007 he was with the Department of Electrical and Computer Engineering at the University of Florida, Gainesville, FL, USA, where he received his Master's degree in electrical and computer engineering in 2007. From 2008 to 2017 he was with the Department of Electrical and Computer Engineering at Drexel University, Philadelphia, PA, USA, where he earned his Ph.D. degree (advisor: Prof. Steven Weber) in electrical engineering in 2014. From 2017 to 2018 he was with the Department of Electrical and Electronic Engineering at Imperial College London, United Kingdom where he worked as a research associate (postdoctoral advisor: Prof. Deniz Gündüz). Since 2021 he has been working as an associate professor in the School of Telecommunications Engineering at Xidian University, Xi'an, China. Having joined the group led by Prof. Baoming Bai, he is affiliated with the State Key laboratory of Integrated Services Networks (ISN).
His research touches upon basic theories of (computer and communication) networks, mathematical modeling of (computer and communication) networks, and to some extent, information theory.
He aspires to seek a better understanding (e.g., fundamental limits, tradeoffs, intrinsic properties) of performance metrics such as delay, stability, throughput, and fairness, in the context of design and performance optimization of networks, and to make contributions to (network) information theory (in the long term).
Specifically he has studied the delay performance of (random linear) network coding: this delay may be formulated as certain extreme order statistic associated with a cellular downlink broadcast scenario. He has also looked at various aspects of the slotted Aloha medium access control protocol including its stability region, as well as throughput and fairness tradeoff.
