I am a senior software engieneer at Bytedance. At Bytedance I am focusing on practical and large-scale recommendation systems. I was previously a data scientist at Baidu Research, Big Data Lab (BDL), under the supervision of Professor Zhang Tong , Dr. Fan Wei and Dr. Wu Haishan.

I obtained my Doctor and Bachelor degree from the Department of Electronic Engineering, Tsinghua University in Jul. 2016 and Jul. 2011, respectively. I worked in lab of NGN and my advisor is Professor Xing Li. I was a visiting student at Sandlab under the supervision of Professor Ben Y. Zhao and Professor Heather Zheng from Sep. 2013 to Aug. 2014(at UC Santa Barbara, but they moved to UChicago in Sep., 2017). I ranked the first place in the college entrance examination of Jiangsu Province in 2007.

My research interests include machine learning, NLP, the analysis and modeling of online social networks, mining large scale of data and Privacy and Security. I worked on graph sampling as an undergraduate student. Here is a list of my publications, or you may visit my Google Scholar.
