I am an assistant professor in the Electrical Engineering and Computer Science Department at the University of Michigan.
My research interests are generally in the areas of programming languages, formal methods, software engineering, and artificial intelligence. I am particularly interested in developing intelligent programming systems that allow programmers and non-programmers to create reliable software easily in a correct-by-construction manner.
Previously I was a researcher at Microsoft. I obtained my Ph.D. from the University of Texas at Austin.

Research

My current research is primarily centered around the topic of program synthesis. This is an emerging field at the intersection of programming systems and artificial intelligence. The basic idea is to make the software development process much easier and more realiable by raising the level of abstraction at which the software behavior is specified. For instance, I have developed several programming-by-example systems that enable end-users to create programs by specifying the desired program's behavior using a few examples. Beyond developing practical systems, I am also excited about understanding the fundamentals of program synthesis. My long-term research goal is to build fundamental intelligent programming techniques that are also useful in practice. Towards this goal, I am currently exploring the following problems.

What are important domains that can benefit from program synthesis and how to build practical systems for these domains?

How to make program synthesis more usable, in particular, by enriching the interaction modalities with human users?

How to design fundamental synthesis algorithms that are general, efficient, generalizable, and multi-modal?
