I study how machines build internal models of the physical world, from 3D geometry and 4D dynamics to structured representations for spatial reasoning.
I am a senior scientist and lecturer at ETH Zürich, working across 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 build models that form and update internal maps to answer three questions: what is where, what changes, and how a machine can interact with its environment.
Before my PhD, I spent seven years (2008 to 2015) building machine learning systems at scale for malware detection at Kaspersky Lab, spanning the full pipeline from data and feature engineering to model selection and deployment. That experience shaped how I think about the long tail and what breaks in deployment, concerns that carry over even as the research questions change.
Methods for reconstructing and rendering photorealistic static and dynamic scenes from sparse or imperfect observations.
Efficient representations for geometry, appearance, motion, and time-varying real-world structure.
Digital representations of humans, biological systems, and surgical scenes: controllable, temporally coherent, and grounded in real observations.
Understanding what kinds of internal maps vision models need to reason about space, motion, and change.
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 foundation models.
