Personal Bio

I m a second-year PhD student in Computer Science at Princeton, working on machine learning and computer vision, particularly on generative models that learn to understand and simulate the 3D world. As an undergraduate, I studied Math and Computer Science at École Polytechnique in France and did research in machine learning, including work on neural rendering and 3D reconstruction. I grew up in Germany, near Frankfurt.

Outside research, I m particularly into running and sailing. I d be very happy to go for a run with a mentee, introduce them to sailing, or just share what I ve learned from studying, doing research, and working in industry across several countries.

Fun Fact

My parents had to forbid me from reading Harry Potter as a kid, because I d read them on a loop. I ve moved on now: Harry Potter and the Methods of Rationality is far better than the original series.

Research Pitch

I work on spatial consistency and understanding for world models. Simple example: video generation models tend to forget what they saw within a few seconds. They lack a spatial understanding of our world - which we need for many downstream applications such as robotics, simulation, etc. This is what I m trying to solve.
