In addition, the research activities include several long-term open-source system development efforts, such as the framework for object-oriented equation-based modeling and simulation of cyberphysical systems, and the high-level programming framework for heterogeneous parallel systems.

Nine full professors, eight associate/assistant professors and several postdocs are involved in the research together with about 25 graduate students.

The is a permanent series of open seminars with topics related to research at the division.

Research is conducted in three laboratories

Codesign and design for testability of embedded/cyberphysical hardware/software systems and formal methods for embedded systems.

Software engineering tools and architectures, large-scale software engineering, model-based software engineering, programming languages and systems, including compilers, debuggers, testing tools, and programming tools for parallel, distributed and real-time systems.

Dependable systems and networks, including reliability, safety and security, resource efficiency with respect to computation capacity, memory, bandwidth and energy.

Education

The division accounts for a significant share of the department's comprehensive undergraduate and master-level education activities, operating about 70 undergraduate/master-level courses per year as well as providing final-thesis supervision. Group of students working on computers..

The undergraduate teaching activities are jointly carried out by the researchers and by the UPP education group for programming and programming didactics, which consists of about ten full-time university teachers and many teaching assistants.

Doctoral studies are offered in the field of Computer Science.
