ABOUT ME

I am an assistant professor in the Faculty of Electrical Engineering, Mathematics, and Computer Science (EEMCS) at Delft University of Technology (TU Delft), the Netherlands. At TU Delft, I direct the AI-enabled Software Engineering (AISE) research lab, where I supervise various PhD, MSc, and BSc students. I am also the lab manager for TU Delft's tenth ICAI lab with industry, AI4SE, a collaboration with Jetbrains consisted of 10 PhDs (and various MSc/BSc and interns). Lastly, I am also part of the Software Engineering Research Group (SERG) at TU Delft.

My research is at the intersection of Natural Language Processing #NLP, deep learning, and source code analysis. I study, design, and develop learning-based models, specifically Large Language Models (#LLM) for source code, to automate software engineering and developer-related tasks such as understanding, generating, and documenting source code. My work has been published by several top venues in the software engineering community such as IEEE/ACM ICSE, EMSE, MSR, ICSME, SANER, and JSS.

I hold a PhD in Software Engineering from Sharif University of Technology (SUT). My PhD research focused on mining information from version control systems to facilitate software production-related tasks by automatically generating reports (such as release notes) for developers and software teams. I have a master's degree in IT Engineering from SUT. My MSc research focused on improving evaluation methods of recommender systems which resulted in various publications.

If you are a researcher working on the intersection of NLP/ML and software engineering and you are interested in my work, please feel free to reach out to propose/discuss possible collaborations.

NOTE for prospective PhD students and postdocs: I have two fully-funded PhD vacancies as well as a postdoc position available on improving development tools and software engineering processes using #LLMs4code. Please apply through the portal for PhD vacancies (link) or reach out to me through my email for the postdoc position. Make sure to introduce yourself, describe your research interests, and enclose a copy of your CV.

NOTE for prospective BSc and MSc students: If you are a TU Delft student who would like to work on the intersection of LLMs and SE in my lab, I have opportunities for thesis, internships, and research projects. Feel free to reach out to me through my email to set up a meeting to discuss potential opportunities. Last but not least, I have limited capacity to supervise MSc/BSc students with scholarships from universities other than TU Delft.
