I am a Ph.D. student in the Computer Science Department at North Carolina State University. I received an M.S. in Computer Science and Engineering from Pohang University of Science and Technology, Pohang, and a B.S. in Computer Science from Ewha Womans University, Seoul, South Korea. In 2003, I entered the Ph.D. program at NCSU, working with Dr. Carla D. Savage and Dr. James C. Lester.

Before entering the Ph.D. program, I worked at Samsung SDS, one of the best IT companies in Korea, and ETRI, a top research center. I was involved in two projects in Samsung SDS, both of which were ERP consulting projects using SAP R/3. My responsibility in these projects was to develop the import module of SAP R/3 and to customize the module to make it suitable for a particular company. In ETRI, I analyzed anti-cyberterror technology, with an emphasis on computer viruses.

My research interests focus on user modeling techniques for intelligent tutoring systems using probabilistic approaches such as Bayesian networks and machine learning. I am also interested in combinatorics and working as a research assistant of Dr. Savage on the Enumerative Combinatorics project which gives me an opportunity for acquiring solid background in the areas of algorithms and theory.

Projects

Partitions and Compositions Defined by Inequalities
Since 2004, I have worked as a research assistant on Enumerative Combinatorics project. For this project, I find and solve the recurrence of listing integer sequences satisfying certain constraints to get the generating function.
