I'm a group leader at HelmholtzAI in Munich and a TUM Junior Fellow working on causality and socially beneficial machine learning.

I obtained my PhD in the Cambridge-Tübingen program co-supervised by Bernhard Schölkopf, Carl Rasmussen, and Adrian Weller. I was an Ellis student and member of Pembroke College, funded by the Cambridge-Tübingen PhD fellowship with generous donations from Microsoft.

During my PhD I interned at Deepmind, Google, and Amazon.

I grew up in Austria, studied Physics and Math in Regensburg, and was fortunate to spend time at Harvard and Stanford during my studies.
