Professor of Computer Science
Joined department: Fall 2001
Professor Xu's current research focuses on the development of virtualization technologies for computer system security and for cloud computing. He has also made early contributions to the area of peer-to-peer media streaming and distribution. He leads the Lab for Research in Emerging Network and Distributed Systems ( FRIENDS).
For computer system security, Xu and his students have been developing virtualization-based systems for capturing, investigating, and defending against stealthy computer malware (e.g., worms, rootkits, and bots). His team is also developing reverse engineering techniques for the analysis of binary artifacts such as binary programs and memory images. For cloud computing, Xu and his students have been developing advanced techniques for the creation, management, and performance optimization of virtual networked infrastructures on top of physical cloud infrastructures.
Xu received four Seed
for Success Awards from Purdue University (2004, 2008,
2008, 2012), a CAREER Award from the National Science
Foundation (2006), and six Best Paper/Best Student Paper Awards from the
International Symposium on Recent Advances in Intrusion
Detection (RAID 2008), ACM Symposium on Cloud Computing
(SoCC 2011), IEEE/ACM International Conference on Automated Software Engineering (ASE 2013), USENIX Security Symposium (2014, Best Student Paper), ACM Conference on Computer and Communications Security (CCS 2015), and Network and Distributed Systems Security Symposium (NDSS 2016). He served on the Editorial Board of the ACM
Transactions on Autonomous and Adaptive Systems (TAAS) and
has served on program committees of major security and cloud computing conferences (e.g., CCS, NDSS,
Oakland, HPDC, and SOCC). He was selected a University
Faculty Scholar in 2012 and has received the College of Science
Undergraduate Advising (2008), Graduate Advising (2014), Leadership (2013), Research (2015), and Team (2015) Awards.
Past and current sponsors of Xu's
