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 five 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). Past and current sponsors of Xu's research include the AFOSR, AFRL, Army CERDEC, DARPA, IARPA, NSA, NSF, ONR, Cisco Systems, DOCOMO USA Labs, ETRI, Microsoft Research, Northrop Grumman, RSA Labs, Southwest Research Institute, and Purdue Research Foundation. He is 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.
