Education & Background
I received my Ph.D. degree in Computer Science from the University of Minnesota, Twin Cities in 2007. I also got the M.S. in Computer Science from the University of Minnesota. For the undergraduate study, I majored Computer Science & Engineering and Statistics at Korea University in (South) Korea. I had worked at Samsung SDS Co. as a software engineer for seven years.
My entire career in both academy and industry is about data and computing. My research areas are data analytics and data management which include skills and technology from database systems, data mining, machine learning and statistics. My research concerns on the development of scalable algorithms for data mining, data management and data-driven knowledge discovery, with a particular emphasis on non-traditional data such as spatial (geospatial), temporal and spatio-temporal data, and graph/network data and scientific data. Location-based computing, services and information are closely related to my fields. I am also interesting in identifying viable data analytics opportunities, and designing, developing and fielding data mining and machine learning solutions that have measurable impact to applications.
Current research projects focus on Big Data analytic methods (e.g., parallel and distributed data analytics algorithms on the MapReduce framework, Hadoop, and on Spark) and Big Data management techniques such as NoSQL and data warehousing in cloud computing environment. Resent works have been presented in the IEEE International Congress on Big Data, the ASE International Conference on Big Data, the IEEE International Conference on Big Data, International Conference on Advances on Big Data Analytics, and so on.
I’m also working for Cyberlearning and Big Data Science technology education.
My research has been supported by the U.S. Air Force Office of Scientific Research, the Air Force Research Laboratory, Purdue Research Foundation, Griffiss Institute/SUNY Research Foundation, Indiana University, and so on. I am an Air Force Faculty Fellow. I have worked as an Air Force Summer Visiting Faculty at the U.S. Air Force Research Laboratory/Rome Research Site. During the last sabbatical, I was a visiting faculty at Korea Advanced Institute of Science and Technology (KAIST), Daejeon, Korea.
I have served as the key organizer or program committee in numerous top-tier international conferences and often as the manuscript reviewer of international journals such as IEEE Transactions on Knowledge and Data Engineering (TKDE) and IEEE Transactions on Knowledge Discovery from Data (TKDD). I have also worked as the review panel of NSF (National Science Foundation) programs such as NSF-CISE and NSF-IIS.
I am leading Data Mining and Big Data Analytics lab. Students, domain experts and industry people are welcome to work with me in all areas of data mining, big data analytics/management, database, machine learning, and related applications.
