Department of Computer Science, Duke University

Hi, I'm Junyang Gao!
Now, I'm a fourth-year Ph.D. student in Computer Science at Duke University, advised by Prof. Jun Yang. My research interests are in Computational Journalism, Temporal Data Processing, Large-scale Data Cleaning and Integration, Spatial Databases, and Machine Learning+Databases.

I interned at Amazon as applied scientist in Summer 2018, working with Dr. Luna Xin Dong and Dr. Xian Li on large-scale knowledge graph accuracy evaluation.

Before joining Duke, I received B.Eng in Computer Science from Tsinghua University (THU), and worked with Prof. Guoliang Li on Location Based Service(LBS) related projects on digital map.
