Call for Participation: we have an ongoing research study to understand how developers change code inside the IDE. If you develop Java code, please participate in our study.

Notice: On Aug 2015 I had a severe bike accident; during my recovery I will not be able to pick up new service, including reviewing for journals and conferences during the second half of 2015 and beginning of 2016. I encourage you to appreciate the gift of life.

In 2007 I got a PhD from the CS department at UIUC. After a postdoct at MIT CSAIL, I moved back to my Alma Mater, where I was a Research Professor. Now I am an Assistant Professor at OSU, living in the beautiful Pacific NW.

Successful software undergoes constant change. My research addresses two important questions:

  1. What changes occur most often in practice?
  2. How can we automate them to improve programmers' productivity and software quality?
Over the years I have successfully automated program transformations to (i) retrofit parallelism into sequential code, (ii) improve responsiveness of mobile apps, (iii) upgrade component-based applications, (iv) update obsolete tests, (v) make end-user programs easier to change.

General interests:- automated refactoring, interactive program analysis and transformation, design & architectural patterns, and broadly interested in concurrency and parallelism, mobile computing, software development processes, program analysis, software testing, and software evolution

Research Impact:

  • my ICSM'05 paper wins the Most Influential Paper Award (N-10 years) at ICSME'15. The citation reads "The ICSM'05 paper has had the most impact and has stood the test of time best, it has had a profound influence on the upcoming field of API analysis."
  • our latest refactorings that empower Java programmers to use lambda expressions are shipping with the official release of the NetBeans IDE.
  • PhD research on record-and-replay of API-level refactoring ships with the official release of the Eclipse IDE and are used by millions of Java developers.
  • the automatic inference of refactorings has been used at large companies like Google and IBM, and dozens of research labs.
  • our ASTGen test generation framework is used in the testing infrastructure at Oracle.
  • empirical studies (one and two) on usage of concurrent libraries have influenced the development of the official libraries in .NET and Java.
  • our resource on learning parallelism in .NET receives more than 150,000 visitors.
  • many years ago I developed the world's first open-source refactoring engine for Java, and was downloaded over 17,000 times.
