I study contact-rich dexterous manipulation under uncertainty, connecting ideas from optimization-based control, risk-sensitive optimization, kinodynamic motion planning, belief estimation, and policy learning to make manipulation with multi-fingered hands more reliable when object pose, friction, contact modes, and target geometry are only partially observed.
My early to mid-career doctoral work studied robust stochastic planning, safe control via distributional reinforcement learning, and multi-agent coordination under uncertainty. More recently, I have taken a certain interest in dexterous grasp synthesis, safe hand control, visuo-tactile policy learning, and uncertainty-aware decision-making for dexterous manipulation, studying how robots (serial chains, humanoids, and mobile manipulators) can estimate uncertainty from proprioceptive, perceptual, and tactile feedback and synthesize controls that balance potentially conflicting performance and safety specifications.
I validate these ideas in simulation using optimization modeling frameworks (CasADi), QP and NLP solvers (qpsolvers, IPOPT), dynamics libraries (Pinocchio), physics-based simulators (MuJoCo, Drake), and reinforcement learning environments (Safety Gymnasium), and on physical hardware comprising serial and branched kinematic chains equipped with proprioception-only and tactile-sensorized multi-fingered hands.

abstract = {Current approaches to estimating the states of agents in multiagent formation tracking relies heavily on either filtering local observations from sensors fitted on each agent, or observations from external sensors in an inertial frame of reference. Such approaches are largely unreliable, centralized, and not practical for real-life settings. Accordingly, we propose a formation tracking scheme that relies on distributed Kalman filtering (DKF) to obtain agents' states. Our approach exploits the underlying shared network to reconstruct the state of each agent by pooling relative state measurements from its neighbors in the network. A weighted consensus-like control law, defined in terms of the computed relative state estimates, is consequently applied to achieve formation maintenance, and a trajectory-error-minimizing controller is designed for the tracking component. Finally, to validate our proposed technique, we present results from numerical simulations and real multi-robot experiments.},
