• Database and Information Systems

    The ongoing digital transformation generates data at a rate that has never been seen before. While these data promise new insights, they also present new challenges to data management and processing. In our group, we address these challenges in the tradition of database systems research. In particular, our focus is on all aspects of query processing, such as optimization algorithms, cardinality estimation, and indexing techniques. Apart from working on relational database system, we also study query processing in property graph database systems.
