I am currently assistant professor in Department of Computer Science and Engineering at University of Bridgeport. I received my Ph.D. in Computer Science from the University of Texas at Arlington in 2006 under Dr. JungHwan Oh's supervising. Previously, I received a BS from Sungkyunkwan University in Mathematic Education and an MS from Sogang University in Computer Science, both of South Korea. Before I pursued my doctorate, I worked as a database administrator for seven years with companies including Boram Bank, Hana Bank and IBM Korea.
