My name is Chenhan Xu. I'm a 1st year Ph.D. student in the Dept. of Computer Science and Engineering, SUNY Buffalo working under the guidance of Prof. Wenyao Xu at the Embedded Sensing and Computing (ESC) Lab. I earned my B. Eng. degree in Network Engineering from NUPT. After graduation, I joined NUPT Center for Learning, Energy and Networks (NCLEN) as a research intern for one year.
