Since October 2015, I have been a Assistant Professor at Beijing Jiaotong University where I drive the broader research activities in mobile computing and Internet of Things. I received a Ph.D. from Institute of Information Engineering of Chinese Academy of Science under the supervision of Limin Sun. My dissertation pioneered pattern recognition techniques for sensing group behavior that enable mobile systems to better cope with diverse user populations encountered in the real-world. More broadly, my research interests revolve around mobile computing and Internet of Things. At heart, I am an experimentalist who likes to build prototype systems based on well-founded computational models.
