Prof. Dr.-Ing. Sebastian Schelter

Sebastian Schelter is a Full Professor at the Berlin Institute on the Foundations of Learning and Data (BIFOLD) and Technische Universität Berlin. His research is focused on the intersection of data management and machine learning with the goal to foster the responsible management of data and to democratise data science technologies.

The research of his group is accompanied by efficient and scalable open source implementations, many of which are applied in real world use cases, for example in the Amazon Web Services cloud and in large European e-commerce platforms.

In the past, he has been an assistant professor at the University of Amsterdam, a faculty fellow at New York University, a senior applied scientist at Amazon Research and a research intern at Twitter and IBM Almaden in California. His research contributions have been recognized with an ACM SIGMOD Systems Award, an ACM SIGMOD Best Demo Runner Up Award, and a Best Paper Runner Up Award from the Table Representation Learning workshop at NeurIPS.

Job Openings

Postdoc Position in Responsible Data Engineering (salary level E14)

We are looking for a postdoc to conduct independent research in responsible data engineering. The research direction should be compatible with the themes of our lab, such as data-centric debugging and testing of machine learning applications, data processing in compliance with legal regulations, or the automation of data validation and preparation for ML. Software and data artifacts resulting from the research should be made available under open source licenses or contributed to existing open source projects.

Further tasks of the position include the collaboration with PhD students, the coordination with other research groups in BIFOLD and external partners, the supervision of master/bachelor theses and teaching activities.

Requirements

  • Successfully completed university degree (Master, Diplom or equivalent) and PhD in computer science or artificial intelligence
  • Strong research background in data management or data-centric machine learning
  • Publication record in international refereed conferences such as SIGMOD, VLDB, SIGIR, ICLR, KDD, NeurIPS or ICML

Desirable

  • Experience in supervising Master/PhD students
  • Teaching experience
