I develop provably robust finite-sample guarantees for reinforcement learning (RL) under uncertainty and adversarial corruption. My current research interests include corruption-tolerant reinforcement learning, robust policy evaluation, distributed and federated reinforcement learning, and minimax lower bounds that characterize the fundamental limits of robust learning.

Research Experience

Graduate Research / Teaching Assistant

North Carolina State University · Aug 2023--Present

• Robust optimal policy learning from corrupted and correlated observations. Showed that vanilla Q-Learning is provably fragile under reward corruption, designed robust Bellman-update methods, and established finite-time convergence with matching minimax lower bounds. Results disseminated across ICML 2026, NeurIPS 2025, and IEEE CDC 2024, CDC 2026.
• Robust policy evaluation under adversarial influences and Markovian data. Developed finite-time theory for robust temporal-difference learning with Markovian noise and function approximation, including upper bounds and near-tight lower bounds. This research is published in AISTATS 2025.
• Robust federated and multi-agent reinforcement learning. Developed adversarially robust and communication-efficient reinforcement learning algorithms for federated multi-agent settings, including Byzantine-resilient methods with collaborative speedups. Two papers published at ACC 2026.

Research Collaboration · Neuromuscular Rehabilitation Engineering Laboratory

University of North Carolina at Chapel Hill · April 2026--Present

• Developing personalized reinforcement learning methods for subject-specific tuning of commercial powered knee prostheses.
• Formulating personalized MDP/CMDP models with user-specific dynamics, time-varying reward design, and safety-comfort constraints.
• Exploring offline-to-online adaptation schemes that warm-start from population priors and enable safe, data-efficient personalization.
