About the Event

Software is increasingly a part of our daily lives, but software errors remain expensive and costly. In this talk we consider three lenses for improving software quality and reducing the cost of software maintenance. We delve into not only approachable human studies (from software readability judgments to medical imaging of developers) but also rigorous and formal proof and invariant techniques (built atop static and dynamic information). We focus, however, on recent results in automated program repair, in which candidate fixes for software bugs are constructed using focused analyses and program transformations. In each case we summarize lessons learned and highlight reproducible research and key insights. Programming languages are the interface between human developers and software systems: program understanding and transformation are powerful levers that can move the world of software quality.


Westley Weimer's primary research interest is advancing software quality through both static and dynamic programming language approaches. He is particularly concerned with automatic or minimally-guided techniques that can scale and be applied easily to large, existing programs. He also works to help programmers address defects, understand programs, and program correctly. His research spans automated program repair, formal verification, program improvement, human studies, and language feature design. He received his PhD from Berkeley and now serves as an associate professor at the University of Virginia. His work has led to over 8,400 citations, eight distinguished paper awards, four multi-conference research awards, and one ten-year most influential paper award. He also enjoys fencing and overacting.
