'Software Engineering' as imagined by 'Microsoft Bing Create'.

Welcome to the Software Maintenance and Analytics Research Team (SMART lab), established at the Faculty of Computer Science of the Dalhousie University. The lab is lead by Tushar Sharma. We research, develop, and disseminate methods, tools, techniques associated with Software engineering (specifically software design and architecture, code quality, refactoring, technical debt, and program comprehension) and machine learning techniques for software engineering applications.
