Programming Languages Researcher


I received my Ph.D. at UCLA Computer Science Department advised by Todd Millstein.


Introduction to Programming and App Development


In the field of programming languages, I would like to contribute towards the design of programming frameworks that allow programs to be specified in as elegant, declarative, and in domain-specific forms as possible, yet be practical enough to have impact in the software community. My main interest is finding practical applications of decision procedures, executable specifications, declarative programming, and constraint solvers in programming. However, my Ph.D. research has focused on utilizing these in software engineering in general: development, testing, debugging, reliability, and education. Aside from their application in the design of languages, I am interested in applying these tools in performing static and dynamic program analyses: verification, synthesis, and program repair.


Let's use constraint solvers not for program-analysis but for program-ming!
