Biography

I am currently a founding engineer at a stealth startup. Previously, I worked as a researcher at MiroMind. I received my M.Phil. degree from The Chinese University of Hong Kong and was fortunate to collaborate with Prof. Yao Lu. Before my graduate studies, I interned with the research team at TuSimple and collaborated with Dr. Naiyan Wang.

My research bridges machine learning and systems, with a focus on algorithm-system co-design to build practical systems. Specifically, I work on:

  1. Efficient RL training frameworks that support training MiroThinker v1.5;
  2. VRAM-channel-aware GPU multiplexing for LLM serving (SGDRC).
