Biography


I am a postdoctoral researcher at Information and Database Systems (IDS) lab, Pohang University of Science and Technology (POSTECH), Republic of Korea.

In Feb 2012, I received my PhD in Computer Science and Engineering at POSTECH under the supervision of Prof. Seung-won Hwang. I was fortunate to work as an intern at Microsoft Research Asia with Dr. Zaiqing Nie and Dr. Ji-Rong Wen and at Microsoft Research with Dr. Emre Kiciman.

My research interests include (1) query processing and optimization in database systems; (2) information retrieval in the Web; (3) data integration and cleansing in large-scale datasets. If you have any questions in my research, feel free to email me.

I am currently seeking a full-time research position job! (CV)
