Education & Background
I received my Ph.D. degree in Computer Science from the University of Minnesota, Twin Cities in 2007. I also received the M.S. in Computer Science from the University of Minnesota in the Twin Cities (of Minneapolis and Saint Paul). For undergraduate study, I majored two areas: Computer Science & Engineering and Statistics in Korea University (KU, or pronounced as Goryeo U in Korea). I worked at Samsung SDS Co. as a software engineer for seven years. Currently, I’m an Associate Professor in Computer Science Department at Purdue University Fort Wayne, and serve as a director in the Computer Science Graduate Program.
My research areas are relevant with data science 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) data, temporal data, graph/network data and scientific data. Current research projects concern big data analytics with parallel and distributed data mining/machine learning algorithms on Hadoop MapReduce and Spark and big data management with techniques such as NoSQL and data warehousing in a cloud computing environment. I am also interesting in identifying viable data science opportunities, and designing, developing and fielding data mining and machine learning solutions that have measurable impact to applications. Students, domain experts and industry people are welcome to work with me in all areas of data mining, big data analytics/management, machine learning, database and related applications.
My research has been supported by the U.S. Air Force Office of Scientific Research, the Air Force Research Laboratory, Microsoft Research, Purdue Research Foundation, Griffiss Institute/SUNY Research Foundation, Indiana University, and so on. I was 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 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.
