I study how machines can build useful internal models of the physical world, from 3D geometry and 4D dynamics to structured representations for spatial reasoning.

About

I am a Senior Scientist at ETH Zürich, working at the intersection of computer vision, computer graphics, and machine learning. My research focuses on representations of real-world 3D and 4D phenomena: reconstructing geometry, modelling motion, rendering photorealistic scenes, and extracting structure from visual observations.

I am increasingly focused on spatial intelligence: the bridge between geometric reconstruction and higher-level reasoning. My goal is to develop models that form and update internal maps to answer fundamental questions: what is where, what changes, and how can a machine interact with its environment?

Research

Spatial intelligence

Understanding what kinds of internal maps vision models need for reasoning about space, objects, motion, navigation, interaction, and change.

Teaching and supervision

At ETH Zürich, I co-teach Computer Vision (with Marc Pollefeys and Siyu Tang) and Digital Humans (with Siyu Tang).

I supervise student projects in computer vision, 3D reconstruction, neural rendering, and spatial intelligence, with particular interest in work that connects rigorous geometric modelling with modern foundation models.

If you are a student interested in working on these topics, please reach out. The most useful messages are short and specific: what you want to work on, why it interests you, and what you have already tried.
