Liu DAI 「戴浏」

Hi, thank you for stopping by :)

I am a senior undergrad at Department of Computer Science, Tongji University.

Currently I'm a research intern at UC San Diego, advised by Prof. Hao Su. Prior to that, I was fortunate to work with Prof. He Wang at Peking University and Prof. Weiwei Guo at Tongji-MIT City Science Lab (CSL@Shanghai).

My research interests lie in Data-Driven Embodied AI in the complex and open world, with a focus on:

  • Generate diverse, interactive and information-rich 3D environments in large scale to support robot learning, especially leveraging generative and foundation models.
  • Develop data-driven and generalizable robot perception and planning algorithms which demonstrate high robustness when being transferred from simulation to the real world.

  • I'm actively looking for a Ph.D. position starting 2024 fall. Please feel free to drop me an email if you're interested in what I do.

    • I'm also an amateur photographer focusing on Documentary Photography and Fine-Art Photography.
      I believe Photography is far more than a tool of recording. It's actually a very expression of our feeling &thinking about this world in silence. I admire works from Vivian Maier, Alex Webb and Alec Soth.
