Biography

I am the research lead at Parameter Lab in Tübingen, Germany. My research interests lie in trustworthy AI, including adversarial machine learning, privacy, alignment, and uncertainty.

I hold a PhD degree in computer science from the University of Luxembourg. My PhD thesis focuses on analyzing the transferability of adversarial examples from the surrogate weight space of DNNs. I am a data scientist who graduated from Ensae ParisTech and a statistician who graduated from Toulouse School of Economics.
