Research

My research interests lie in the general area of software engineering, with particular emphasis on automated program repair. My work draws on data mining, program analysis, and fault localization and aims to improve the automated program repair agenda towards boosting its adaption by practitioners.

Projects:
Learning from Contributions

Gather and analyze various communication data in software development towards learning contributions and relate them to the characteristics of the software products and processes.

Mining software repositories towards understanding code change properties to guide program repair

Building an automated program repair-adapted representation of code that will be leveraged to associate the change intention to various artifacts such as bug reports, test cases.

Developing a History Based Vulnerability Fixer by Leveraging Developer Anomalies

Explore state of the art program repair approaches and learn patterns by capturing the context and the semantic properties in order to identify recurrent patterns of fixes for common security vulnerabilities.

The impact of Covid-19 in open source software development

Investigate the impact of Covid-19 in open source development ecosystems on GitHub. Starting with the construction of a large data set on the subject, we will be conducting experiments in order to understand what this crisis has generated and its impact on the habits, productivity of developers.
