Professor

Michael GodfreyResearch interests

Professor Godfrey's research interests span several areas of empirical software engineering including software evolution, mining software repositories and software analytics, code clone analysis, software architecture recovery and modeling, and reverse engineering.

To better understand how and why software systems evolve over time, Professor Godfrey and his students have been developing theories, techniques, and tools for studying software change. This has included the study of emergent properties of software systems, analysis of code duplication (cloning), software artifact provenance, software architecture recovery and modelling, and tools for modeling and understanding changing systems.

Industrial and sabbatical experience

Since returning to Canada in 1998, Professor Godfrey has been a co-PI in several NSERC-sponsored industrial research grants from Nortel Networks, Sun Microsystems, IBM, and CA.

During the academic year 2003-04, he spent a sabbatical as Visiting Researcher at Sun Microsystems Labs in Mountain View, California, where he worked on the Jackpot static analysis tool with James Gosling, and also co-designed and co-implemented the SALSA analysis tool for J2EE systems with John Crupi. 

During the academic year 2011-2012, he spent a sabbatical as Distinguished Scientist at CWI in the Netherlands, working with the RASCAL program transformation group led by Jurgen Vinju and Paul Klint.
