I am a postdoctoral research scientist at POSTECH GSAI, working with Professor Wook-Shin Han. I received my Ph.D. degree in Computer Science and Engineering at POSTECH under the supervision of Professor Wook-Shin Han. Prior to this, I received my B.S. degree in Software Engineering at Sungkyunkwan University. My research interests include big data processing, database systems, query processing, and query optimization. Recently, I have been committed to developing new techniques to improve the ability of Apache Spark to process a massive number of small queries efficiently.
