I am a Senior ML Researcher at Apple. My main research interest lies at the intersection of data management and AI/ML systems, with a particular focus on how to efficiently, reliably, and responsibly use and manage data throughout the development, evaluation, and operational phase of AI/ML-based solutions.

Starting Fall 2025, I will also be an external lecturer at ETH co-teaching a seminar on Systems for AI with Ana Klimovic.

Previously, I was a PostDoc in the Data Systems and Theory group lead by Dan Olteanu at UZH and defended my thesis at ETH Zurich’s System Group under the supervision of Ce Zhang. I hold a bachelor’s degree from the Bern University of Applied Sciences and received my MSc in Computer Science from ETH Zurich. During my PhD, I have worked as a research intern and student research consultant at Google Brain (now Google DeepMind).
