Sebastian is a PhD student at the Information Systems Group at the Hasso Plattner Institute, Potsdam, Germany. This is where he also did his Master’s degree in IT systems engineering. In general, he’s passionate and excited about leading edge data processing technology, efficient algorithms, and elegant system designs. More concretely, his main line of research focuses on distributed algorithms to discover dependencies from data—these are problems of high runtime and space complexity that must be tackled with the greatest care. While interning at the Data Analytics Group at the Qatar Research Computing Institute, he further picked up the topic of integrating heterogeneous data processing platforms and played a leading role in the design and implementation of Rheem. Last but not least, he’s devoted to open source software. Not only have most of his research project outcomes been open sourced (Rheem, in particular), but he also contributes to Apache projects.
