Prior to this position he was a Research Fellow at Queen's University (Canada), working with the Software Reengineering Research Group and the NSERC/RIM Industrial Research Chair in Software Engineering of Ultra Large Scale Systems. He received his Ph.D in Software Engineering from the University of Montreal in 2010, under the supervision of Yann-Gaël Guéhéneuc. His main research interest is in the field of empirical software engineering, with an emphasis on developing techniques and tools to improve software quality. Over the years, he has applied many text mining techniques to solve multiple software engineering problems. He co-founded the International Workshop on Release Engineering and was one of the editors of the first special issue on Release Engineering in the IEEE Software magazine.
