Yannic Noller

Professor for Software Quality, Ruhr University Bochum (RUB)


UPDATE: I recently joined the Ruhr-University Bochum! I will hire PhD students for my new group, let me know if you want to work with me!

Yannic (CV) is a professor at the faculty of computer science at the Ruhr University Bochum (RUB) and leads the chair for Software Quality. His research focuses on how software quality can be maintained and improved with automated testing and repair technologies. The general research goal is to shape the future of software development by contributing to the domain of automated software engineering and providing the means to develop reliable, trustworthy, and secure software systems. In particular, he works in the following areas:

Research Topics

  1. Automated Program Repair: developing new repair techniques to aid developers in fixing program bugs
  2. Machine Learning Analysis: automated analysis, testing, and repairing of machine learning models
  3. Software Testing: exploring and designing (hybrid) testing techniques to systematically generate test inputs that expose incorrect program behavior
  4. Intelligent Tutoring Systems: how to help CS students learn programming by applying concepts from automated testing and repair to guide the students toward the right solution
  5. Human Factors in SE: studying developer needs and requirements for successful deployment of testing and repair techniques in development practice

His Ph.D. work focused on differential software testing, in particular, by combining fuzzing and symbolic execution in the context of regression analysis, algorithmic complexity analysis, side-channel analysis, and robustness analysis of neural networks.


Jul 01, 2024 After almost 4 years in Singapore 🇸🇬, I returned to Germany 🇩🇪 and joined the Ruhr-University Bochum as professor in the faculty of computer science!
Feb 09, 2024 Happy to be the Publicity Co-Chair for ISSTA 2025!🇳🇴🥳 If you also want to contribute, here is your chance! ISSTA is looking for competent and motivated reviewers for its 2025 edition. Nominate yourself (deadline Feb 20) using this form: https://t.co/BAxK2wN1V9.
Jan 20, 2024 Happy to share that our poster about “Exploring Complexity Estimation with Symbolic Execution and Large Language Models” has been accepted for the KLEE Workshop 2024!
Jan 18, 2024 I had fun participating in STEAMxD @ SUTD and teaching Singapore’s bright JC students about basic principles in machine learning!
Dec 07, 2023 Our work on “Evolutionary Testing for Program Repair” has been accepted for ICST 2024! With EvoRepair, we explore a coevolution approach that generates tests and repairs in a unified workflow using EvoSuite. Stay tuned for the pre-print :-)
