I am a full professor and the head of the DAST (Data Systems and Theory) group at the Department of Informatics, University of Zurich.
I spend my time understanding computational challenges on data processing and designing simple and scalable solutions towards these challenges.
My theoretical research includes the development of novel data processing algorithms and of data processing languages along with the analysis of their complexities. My systems research is on building data systems in academia and industry based on well-understood theory.
My contributions are on theoretical foundations and systems aspects of data processing, including XML query processing, incomplete information and probabilistic databases, factorised databases, machine learning over relational data, incremental maintenance for database and machine learning, and the commercial systems LogicBlox and relationalAI.
I currently serve as associate editor for the following journals:
- Since September 2019: SIGMOD Record Database Principles column
- Since January 2018: ACM Transactions on Database Systems (TODS)
- April 2019 - March 2020: Proceedings of Very Large Data Bases (PVLDB)
I serve as PC chair for International Conference on Database Theory (ICDT) 2022 and as tutorial chair for EDBT/ICDT 2020.
