I am a research scientist in the Computational Cognitive Science group in the Brain and Cognitive Sciences department at MIT.

I study how we perceive, reason about, and interact with our everyday surroundings. From just a glance, a recollection, or a few words, we can know so much: what objects are where; whether they are movable, fragile, slimy, or hot; whether they were made by a machine, by hand, or by nature; whether they are broken, how they could be repaired; and so on. My research focuses on the computations by which our brains build up these rich and abstract mental representations of a scene, along with its objects, materials, and dynamics, and how these representations are used by our broader cognitive faculties to orchestrate complex behaviors.
