About Me
I do software research. My students and I create tools and techniques that help developers build better software—by automatically testing, analyzing, and debugging its code and its development process.
Our approaches have proven quite influential in academia and industry. My Curriculum Vitae lists the most important achievements.

Current Projects
Our research projects involve generating software tests, automated debugging and repair, analyzing mobile systems, analyzing user interfaces, and more. Essentially, our research focuses on the following questions:
- How can we systematically test complex software systems?
- How can we accurately determine and characterize input formats?
- How can we explain causes and circumstances of software failures?
Our solutions typically apply and combine several techniques including dynamic analysis, static analysis, specification mining, test generation, natural language processing, machine learning, and formal languages.
My largest project in 2020 was The Fuzzing Book—an interactive textbook on test generation (“fuzzing”) techniques. You can execute and edit the code right in your browser. In 2021, I published The Debugging Book, which presents and implements a number of techniques for automated debugging and repair.
Current Papers
My papers can be found on Google Scholar, in the ACM Digital Library, and in DBLP. For recent works and preprints, check out my CISPA publication list.
Current Courses
- In Winter 2020/21, we offer an advanced course on automated debugging, based on a The Debugging Book, a new book on automated debugging.
- In Summer 2021, we offer seminars around automated testing and debugging.
- In Winter 2021/22, we plan to re-offer our advanced course on security testing, based on The Fuzzing Book.
Check out our courses here.
My Group
At CISPA and Saarland University, I work with great students and Post-Docs from across the world on cutting-edge research.
We are constantly looking out for great students and Postdocs. Our positions are well paid and allow for highly productive research. If you’re interested in a PhD or Postdoc position, please apply at CISPA and state your specific interests.
Theses
If you are a student of Saarland University and have fun with automated program analysis, testing, and debugging, you might want to do a thesis with us. Here are the details on how to do a thesis with us.

Watch Me
I am a frequent speaker at events. Here are two recorded talks I am particularly proud of.
2020: Learning the Language of Failure
In my 2020 CASA Distinguished Lecture “Learning the Language of Failure”, I show some highlights of our current work:
- how to automatically learn circumstances of a given failure, expressed over features of input elements;
- how to automatically infer input languages as readable grammars, and how to use them for massive fuzzing; and
- how to systematically and precisely characterize the set of inputs that causes a given failure – the “language of failure”.
Enjoy the show! Annotated slides are available, too.
2018: Outstanding Research Award Keynote
These days, I also spend quite some time giving career advice. In my ICSE 2018 SIGSOFT Award keynote, I unfold three lessons on impact in software engineering research:
- Do relevant work
- Strive for simplicity
- Keep on innovating
Again, detailed slides and full manuscript are available.
