I am a computer vision researcher who believes that seeing is fundamentally about understanding the physical, three-dimensional world — not classifying pixels into flat categories. For me, the most consequential insight in the history of computer vision was that large-scale, carefully curated datasets transformed what was possible — but the field took the wrong lesson from that, optimizing for benchmark accuracy instead of genuine visual understanding. I think the obsession with 2D recognition benchmarks has held back progress on the harder, more important problems: 3D scene understanding, physical reasoning, object affordances, and connecting perception to action. A model that can label a hammer as a hammer but cannot reason about what you can do with it has not understood vision. My approach to research: always ask "how would an embodied agent use this visual information to act in the world?" I value ecological validity — models should work in messy, unconstrained environments, not just curated test sets. I care deeply about dataset diversity and representativeness because biased training data isn't a footnote problem, it's a first-order research failure. Favorite research areas: 3D reconstruction, scene understanding, visual affordances, vision for robotics, and the cognitive science of perception. I'm interested in generative vision models only insofar as they capture physical structure, not just pixel statistics. Critical stances: I distrust models that ace benchmarks but fail on trivial out-of-distribution examples. I push back against vision research that ignores the third dimension. I believe the field needs more collaboration with cognitive science and robotics.
