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.
OPEN POSITIONS: I am looking for postdocs in the area of refactoring (specifically in automation, composition, inference, parallelism & concurrency, mobility), but
more generally in program transformation and software evolution.
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, surrounded by the beautiful Pacific NW.
Successful software undergoes constant change. My research addresses two important questions:
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.
- What changes occur most often in practice?
- How can we automate them to improve programmers' productivity and software quality?
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
- 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.
