Tongji Intelligence, Embodiment and Vision Lab (TIEV)

I am a tenured Associate Professor in the School of Computer Science and Technology at Tongji University. My research focuses on spatial and embodied intelligence, with memory mechanisms as a unifying theme.

Our work spans spatiotemporal reconstruction, foundation models, continual learning, reinforcement learning, safe decision-making, intelligent agents, and robotic systems. We study how memory helps these systems understand changing environments, learn from experience, and act safely over the long term.

  • Spatiotemporal reconstruction and spatial memory
  • Foundation models and continual learning
  • Reinforcement learning and safe decision-making
  • Intelligent agents and robotic systems
