What Is the CaCTüS Internship Program?
CaCTüS stands for Computation and Cognition Tübingen Summer Internship.
It is a research internship designed to help talented students gain experience in modern scientific research.
The programme focuses on subjects connected with artificial intelligence and biological intelligence.
These fields examine how intelligent systems learn, process information, make decisions and respond to their environments.
For example, researchers may study machine learning algorithms, brain activity, perception, human behavior or computational models.
Selected interns work directly with scientists on research projects.
They also become part of a research community where they can develop technical skills, exchange ideas and explore future academic opportunities.
A major objective of CaCTüS is to improve access to high-quality scientific research.
Therefore, the programme particularly supports students who face barriers to educational and professional development.
Host Institutions
