Research

I am working on two directions, namely (1) system-wide composition, testing and analysis techniques, and (2) green computing.
I has no longer maintained the list on my website. 

 
Good news

  • Our web service testing paper is featured as the spotlight article of the IEEE Transactiosn on Services Computing Sep/Oct 2015 issue.

Tools

  • Some tools implemented by our research group. 

Old stuff
My core research area is software analysis and testing, and I plan to go deeper into the programming system side in the coming few years. In terms of application areas, I mainly study service-based systems, pervasive computing applications, and concurrent systems. Here is a list of selected sub-topic that I am currently exploring, and, for each topic, I just list out some recent publications to ease you to follow my work.

  1. Concurrency Bug Detection [ISSTA'12, ICSE'12, ISSRE'11, ICSE'10, FSE'08, FSE'07, FSE'06, ICSE'06]
  2. Testing of Context-aware Programs [TOSEM10, QSIC'10, ASE'09, ICSE’08, FSE'08, ICDCS'08]
  3. Testing and Analysis of Service-Oriented Programs [COMPSAC'12, JSS'11, ICWS'10, WWW'09, TSE'09, FSE'09, ICSE'08]
  4. Fault Localization in Programs [SPE12, JSS11, IST09, FSE’09, ICSE’09]
  5. Cloud Computing [APSCC’09, APSCC’08]
  6. Program Testing by Diversificaiton and Randomization [ASE'09, SQJ'08]
  7. Service Selection [SOSE'10, ICWS’08]
  8. Integration of Testing and Debugging [IST'12, QSIC'11, IWPDC'10]
  9. Energy Saving [JSS'11]

I like to understand the underlying reasons on why a model works. My next move is to explore the following topics:

  • Bug Detection in Concurrent Systems
  • Energy and Green IT
  • SE/PL issues in Cloud Computing 

 
The application domains are:

  • Services computing
  • Self-adaptive systems
  • Cyber physical system
  • Typical concurrent software and systems
  • Large components
