My research is in Software Engineering, inspired/informed by program analysis and transformation, with a side of search-based software engineering. I focus on automatic program improvement and repair (using stochastic or search based as well as more formal approaches such as SMT-informed semantic code search); assurance and testing, especially in light of the scale and complexity of modern evolving systems; and quality metrics.  I study software from the worlds of open source and desktop all the way to embedded and robotics systems.

Recent project links/websites

This list is not comprehensive, but I get the most email about these.  Note that virtually all of my work is done in collaboration with many great colleagues and students!

SearchRepair: extends and then uses semantic code search over large repositories of candidate code bases to produce high-quality bug patches. (see paper, github)

GenProg: combines stochastic search methods like genetic programming with lightweight program analyses to find patches for real bugs in extant software. The main website provides an overview; a publication list; demo videos; and source code, benchmarks, workloads, and experimental reproduction instructions for all GenProg-related research.

Empirical evaluations: the ManyBugs and IntroClass benchmarks are intended to support evaluations of program repair research. A recent use of the latter established (interesting!) limits and challenges in existing state-of-the-art automated patch generation (see paper and project site).


By default, Bibtex will butcher my last name (turning me into Goues, C.L.); I always appreciate judiciously applied brackets ({Le Goues}) or a non-breaking space (Le~Goues).

I endeavor to keep this list up to date, though DBLP and Google Scholar are also good places to look.
