I'm currently at Wizard Quant, working on recursive self-improvement (RSI). My focus is on accelerating self-improving loops through reliable and efficient distributed training, evaluation, and data infrastructure.

I'm an open-source contributor to vLLM, SGLang, Transformers, Megatron-LM, and PyTorch. My research appears in Nature, NeurIPS, and EMNLP, and has been adopted across OpenAI, Anthropic, Google, and xAI. I have reviewed for Manning Publications, NeurIPS and ACL Rolling Review. Previously I worked with UIUC MLSys, received the David R. Cheriton Fellowship at UWaterloo, and graduated summa cum laude from SUSTech.

I share tech thoughts on Zhihu and travel moments on Instagram. Feel free to email me for research discussions, collaborations, or whatever else.
