Dr. Ling Liu is a Professor in the College of Computing at Georgia Institute of Technology. There she directs the research programs in Distributed Data Intensive Systems Lab (DiSL), examining performance, security, privacy, and data management issues in building large scale distributed computing systems. Dr. Liu and the DiSL research group have been working on various aspects of distributed data intensive systems, ranging from decentralized overlay networks, mobile computing and location based services, sensor network and event stream processing, to service oriented computing and architectures. She has published over 200 international journal and conference articles in the areas of Internet Computing systems, Internet data management, distributed systems, and information security. Her research group has produced a number of open source software systems, among which the most popular ones include WebCQ, XWRAPElite, PeerCrawl. Dr. Liu is the recipient of the best paper award of ICDCS 2003 and the best paper award of WWW 2004, and a recipient of 2005 Pat Goldberg Memorial Best Paper Award.

Dr. Ling Liu is an internationally recognized expert in the areas of Database Systems, Distributed Computing, Internet Systems, and Service oriented computing. She has chaired a number of conferences as a PC chair, vice PC chair, or a general chair, including IEEE International Conference on Data Engineering (ICDE 2004, ICDE 2006, ICDE 2007), IEEE International Conference on Distributed Computing (ICDCS 2006), IEEE International Conference on Web Services (ICWS 2004), CreateNet-ICST Collaborative Computing Conference (CollaborateCom 2005, 2006), ACM International Conference on Knowledge and Information Management (CIKM 2000). Dr. Liu is currently on the editorial board of several international journals, including IEEE Transactions on Knowledge and Data Engineering, International Journal of Peer-to-Peer Networking and Applications (Springer), International Journal of Very Large Database systems (Springer), International Journal of Web Services Research, Wireless Network Journal (WINET). Dr. Liu’s research is primarily sponsored by NSF, DoE, DARPA, IBM, and HP. Dr. Liu is a recipient of IBM Faculty Award (2003, 2006, 2007).
