I am a PhD student at MIT working with Professor Pulkit Agrawal in the Improbable AI lab. I am currently investigating how tactile perception can enable more accurate and dexterous robotic manipulation. I did my Masters with Professor Alberto Rodriguez in the MCube Lab, and have also spent time at Mitsubishi Electric Research Labs (MERL).
I am interested in physical robot intelligence, and in particular, the role of tactile feedback in reactive control of dexterous manipulation. My recent work has centered on perception algorithms that estimate object pose from tactile images, to enable precise manipulation tasks.

Our framework estimates and tracks object pose using tactile images while simultaneously generating motion plans to achieve manipulation objectives.
High-Accuracy Tactile Pose Estimation for Small Parts Assembly (coming soon!) Antonia Bronars,
Devesh Jha,
Radu Corcodel In preparation
We assemble tight-tolerance industrial connectors using a only simple controller, without the need for specialized search or insertion algorithms. This is possible via sub-millimeter accuracy tactile pose estimation.
simPLE learns to pick, regrasp, and place objects precisely given the object CAD model. We develop three main components: task-aware grasping, visuotactile perception, and regrasp planning.

Given an object's CAD model, we learn a tailored perception model in simulation that estimates a probability distribution over possible object poses given a real tactile observation. Our solution is used by Magna, ABB, and MERL.
Gliding Motions of a Rigid Body: The Curious Dynamics of Littlewood's Rolling Hoop Antonia Bronars,

paper
We analyze the self-induced jumping behavior of a rolling hoop, and show that the paradoxical motions - first noted by mathematician John Littlewood - are consistent with the principles of mechanics.
