Wang-Chien Lee

Wang-Chien Lee received his B.S. in information science at the National Chiao Tung University, Taiwan, his M.S. in computer science at Indiana University, and his Ph.D. in computer and information science at Ohio State University. He joined Penn State as an associate professor of computer science and engineering in spring 2002. Prior to this, he spent over five years as a member of the technical staff at Verizon/GTE Laboratories, Inc.
Dr. Lee performs cross-area research in database systems, pervasive/mobile computing, and networking, with a special interest in spatial, temporal and multi-dimensional aspects. His work involves development of data management techniques for supporting complex queries in a wide spectrum of networking and mobile computing environments (such as wireless sensor networks, peer-to-peer networks, and wireless broadcast systems). Meanwhile, he works on information integration/retrieval, XML, security, and object-oriented databases. He has published more than 120 technical papers on these topics.
Dr. Lee's research has been supported by multiple NSF grants. Most of his research result has been published in prestigious journals and conferences in the fields of databases, mobile computing and networking. He has been active in various IEEE/ACM conferences and has given tutorials for major conferences on mobile databases, wireless sensor networks, peer-to-peer computing, and location-based services. He was the founding program co-chair of the International Conference on Mobile Data Management. He has also served as a guest editor for several journal special issues (e.g., IEEE Transactions on Computers) on mobile database related topics. He is currently serving as the program co-chair of the Second International Conference on Scalable Information Systems (Infoscale'07) and the general co-chair of the Sixth International ACM Workshop on Data Engineering for Wireless and Mobile Access (MobiDE'07).
