∑ Iím serving as a program committee for the 22th ACM SIGSPATIAL International Conference on Advances in Geographic Information Systems (ACM SIGSPATIAL GIS 2014), Dallas, Texas, November 4 to 7, 2014. ACM SIGSPAITAL GIS aims bringing together researchers, developers and users in relation to theory and systems based on geo-spatial data and knowledge and discussing for advances of computer science in geographic information systems.
I received the Ph.D. in Computer Science at University of Minnesota, Minneapolis, in 2007. I also got the Master degree in Computer Science at University of Minnesota.† I have two Bachelor degrees in Computer Science & Engineering, and Statistics from Korea University in (South) Korea.
My research area is databases and data mining. Iím working for data management and computational analytic methods (data mining, machine learning, and statistics) for nontraditional data such as spatial, temporal and spatio-temporal data (including moving object data), graph/network data, and scientific data. Location based computing, information and services are closely related. Iím directing the Knowledge discovery, Data mining and Database Lab. Current research projects concern Big Data analytic methods (e.g., parallel and distributed mining methods on Hadoop framework) and Big Data management techniques (e.g., NoSQL, distributed database systems and data warehousing) on cloud computing environment. Students are welcome to work with me in all areas of data mining, database and related applications.
