Nikolaos Tsantalis

Nikolaos Tsantalis is a Professor in the Department of Computer Science and Software Engineering. He serves as Associate Chair for Software Engineering and focuses on advancing software engineering practices through automated refactoring tools, empirical studies, and code quality analysis. His work emphasizes improving software maintainability, design quality, and developer productivity.

Research Interests:

• Automated Refactoring (e.g., RefactoringMiner, JDeodorant)
• Code Smells and Design Patterns
• Empirical Studies on Refactoring
• Tool Support for Software Evolution
• Code Diffing and Tracking
• IDE Integration for Refactoring

Key Contributions: Developed RefactoringMiner (2020), a tool for detecting refactoring operations in commit histories, and JDeodorant, a static analysis tool for identifying and resolving class-level design smells. His recent work explores leveraging LLMs and semantic embeddings for automated refactoring.

Advising/Grants: No students are explicitly listed, but Tsantalis has contributed to numerous tool-based projects funded through academic collaborations. His research spans industry-academia partnerships to improve software development workflows.

Labs/Teams: Leads research on automated refactoring and software maintenance through collaborations with IDE vendors and open-source communities.
