Biographical Sketch



I am a Ph.D. student in Computer Science at Duke University. I am interested in interdisciplinary research in machine learning and datacenter management. I design statistical/neural learning models toward intelligent analysis of large-scale datacenters. I also work on reinforcement learning (or dynamic programming) based datacenter scheduling and resource allocation algorithms. My advisor is Benjamin C. Lee, who is an Associate Professor of Electrical & Computer Engineering and an Associate Professor of Computer Science at Duke University.


As a research intern, I am delighted to work with Dr. Kim Hazelwood at Facebook during the summer of 2017 and 2018. Dr. Hazelwood work at the interface between systems and machine learning, and servers as a manager at Facebook AI Infra Foundation and Facebook Research. My intern project is about understanding datacenter workloads at Facebook's scale with graph thoery and probabilistic semantic learning algorithms. During my internship, I also work closely with Dr. David Brooks, who is a Professor in Computer Science at Harvard University, and Dr. Xiaodong Wang, who is a Research Scientist at Facebook Applied Machine Learning. After internship, I have been working for Facebook as a part-time researcher.


Before joining Duke, I studied Computer Science at  Xi'an Jiaotong University (XJTU). At XJTU, I worked on modeling computer system with statistical learning and econometric theories. As a student, I also visited The Institute of Computing Technology, Chinese Academy of Sciences, and the Trustworthy and Intelligent Internet Computing Laboratory, The Chinese University of Hong Kong for joint research projects.
