Joined Ruhr-Universität Bochum as Junior Professor of Databases and Information Systems
I am building a research group on next-generation data systems that combine classical data system principles with modern AI techniques. Openings for PhD students and student assistants will be announced here.
- Paper
Towards Multimodal Stream Processing Systems presented at EDBT 2026
A vision for streaming systems that treat multimodal LLMs as first-class operators, so queries can run in real time over text, images, audio and sensor data together.

Two papers on learned cost models in PVLDB 2025: Opening the Black-Box and Learned Cost Models for Query Optimization
Opening the Black-Box: Explaining Learned Cost Models for Databases brings explainability techniques to learned cost models, and Learned Cost Models for Query Optimization: From Batch to Streaming Systems carries them over to streaming workloads.
- Paper
How Good are Learned Cost Models, Really? published at SIGMOD 2025
A study of learned cost models on the query optimization tasks they are meant to support, rather than on estimation accuracy alone.
- Award
Named an Athene Young Investigator at TU Darmstadt
The programme supports early-career researchers in leading their own junior research group.
