About me

I moved to Bremen.

Prior to moving up north, I used to be a PhD student heading the [mc]square project. [mc]square is a verification platform for microcontroller binary code. The key idea in [mc]square is to combine different formal methods in order to analyze hardware-specific microcontroller code. My own focus is the development of static analysis and abtract interpretation techniques specifically suited for verifying bit-twiddling programs. I am also involved in the CEVTES project, which is a joint project with the TU Vienna and the UAS Technikum Vienna on test-case generation for binary code.

Before I joined the Embedded Software Laboratory, I received my diploma degree from the Christian-Albrechts University of Kiel and visited NICTA in Sydney, Australia. At NICTA, I worked on Goanna, a static analyzer for the C/C++ programming languages.

See my CV for more details.

Research Interests

abstract interpretation of bit-vector programs (see [mc]square), in particular using automatic abstraction
relational abstract domains
formal verification
software model checking
software for embedded systems

In summary, I combine theoretical computer science with low-level programming, for example, by automatically deriving invariants for bit-twiddling binary code. I particularly enjoy utilizing SAT/SMT solvers for solving such problems. If you interested in this topic, you might want to check out my SAS'10 paper or my ESOP'11 paper, which give a good feel about how precise SAT-based abstract interpretation of bit-vector programs (such as assembly code) can get. However, to make such techniques scale, you need to apply certain other techniques, such as the projection algorithm from my CAV'11 paper.

Professional Activities

Symposium co-chair for the Symposium on Design & Verification Methodologies for Embedded Systems, which is a symposium within the IEEE/ASME International Conference on Mechatronic and Embedded Systems and Applications (MESA) 2012 in Suzhou, China.
Co-chair of the 6th International Workshop on Systems Software Verification (SSV 2011) in Nijmegen, The Netherlands.
Co-chair for the 4th Symposium on Design & Verification Tools for Embedded Systems (DVTES 2011) at IEEE/ASME International Conference on Mechatronic and Embedded Systems and Applications (MESA) 2011 in Washington DC, USA
Program committee for the 15th International Workshop on Formal Methods for Industrial Critical Systems (FMICS 2010) in Antwerp, Belgium
Local organizer for the 4th International Workshop on Systems Software Verification (SSV 2009) in Aachen, Germany

B.Sc./M.Sc./Diploma Theses

We always have a number of different topics for diploma, bachelors, and masters theses in the [mc]square project. Even though I do not supervise theses myself anymore, please contact me if you are interested in working on verification in the field of embedded software, preferably via email. We can probably find an interesting topic and a supervisor.
