Your tasks

Graphs are a fundamental data structure and are commonly used to model relationships between data points such as links between web pages or friendships between users in a social network. Due to the large variety in data science tasks performed with graph-structured data, different specialized systems have been developed, such as graph processing frameworks, graph databases, graph learning frameworks, knowledge graph systems, and graph mining systems. While each of them is specialized on a specific type of task and is highly efficient for it, maintaining and integrating a zoo of graph data systems is a huge challenge and leaves a lot of room for optimizations.

Our vision is to explore opportunities to unify core parts of the different types of systems and develop a core graph data system that can serve as a common building block. This way, redundancies in keeping multiple copies of graph data in different systems could be reduced, maintenance of the systems could be improved, and operational costs could be optimized. To perform this exciting research, we are looking for a highly motivated student or PostDoc who has recently finished his/her Master’s degree or PhD degree in computer science.

The position is fixed-term according to the “Wissenschaftszeitvertragsgesetz” and serves the own scientific qualification (doctorate) with remuneration according to pay group 13 TV-L, as far as the employment takes place in an employment contract. As a post-doc with a completed doctorate, employment as an academic councillor in temporary civil service in grade A13 is possible for an initial period of three years. In all other respects, the hiring requirements according to the Bavarian University Innovation Act (BayHIG) apply.

We offer

  • Work in a highly innovative environment
  • Supervision at one of the leading universities of Germany
  • Funds for travel and student assistants (HiWis) are available
  • We will consider all incoming applications until the position is filled.
