Rajshakhar Paul

I am a 3rd year Computer Science PhD student at Wayne State University, working at the SEAL Lab under the supervision of Dr. Amiangshu Bosu. My research interest focuses on Data-Driven Software Engineering. Currently, I am working on Software Vulnerability Detection using peer code review data of FLOSS projects. Prior to joining WSU, I was an MS student at SIUC. I completed my BS in Computer Science and Engineering from Bangladesh University of Engineering and Technology.

Selected Research Projects

  • Improving the Effectiveness of Code Reviews in Identifying Security Defects

    The project aims at improving the effectiveness of code review in identifying security defects. With this goal, we are using code review data from several Open Source Software (OSS) projects to analyze the characteristics of code reviews that can successfully identify security defects. With the knowledge of this study, we aim to identify better strategies to do security code review.

  • Real-Time Identification of Potential Security Vulnerability Occurance

    This project aims at identifying a potential security vulnerability once the vulnerable code change appears in code review. With this goal, we are building machine learning-based models to automatically identify a code review as soon as a security concern appears in the code review discussion.

  • Identifing the Differences in Expressions of Sentiments between Male and Female Developers during Code Review

    This study identifies the differences in expressions of sentiments between male and female developers during various software engineering tasks. With this goal, we mined the code review repositories of six popular OSS projects. We used a semi-automated approach leveraging the name as well as multiple social networks to identify the gender of a developer. Using SentiSE, a customized and state-of-the-art sentiment analysis tool for the software engineering domain, we classify each communication as negative, positive, or neutral. We also compute the frequencies of sentiment words, emoticons, and expletives used by each developer. Our results suggest that the likelihood of using sentiment words, emoticons, and expletives during code reviews varies based on the gender of a developer.
