Research

My research investigates trustworthy artificial intelligence for decision-making, focusing on the intersection of deep reinforcement learning, embodied control, and large language models. My core research interests include:

  • Deep Reinforcement Learning: Developing robust algorithms for sequential decision-making in complex, high-dimensional spaces.
  • Robotics & Control: Investigating learning-based control strategies and representation learning for embodied agents.
  • Agentic AI: Designing reasoning frameworks and human-in-the-loop learning pipelines for autonomous systems.
  • Quantum Machine Learning (Actively learning): Exploring the theoretical and practical intersections of quantum computing methodologies and artificial intelligence.
