I'm currently at Wizard Quant, working on recursive self-improvement (RSI) for foundation models. My focus is on training and evaluation reliability and efficiency, maximizing iteration velocity across self-improving loops.
My research appears in Nature, NeurIPS, and EMNLP, and has been adopted across OpenAI, Anthropic, Google, and xAI. Previously with UIUC MLSys, awarded the David R. Cheriton Fellowship at UWaterloo, and graduated summa cum laude from SUSTech.
My work spans distributed training, inference, evaluation, and data infrastructure. I am an open-source enthusiast and have contributed to projects including vLLM, SGLang, Transformers, Megatron-LM, PyTorch, and RisingWave.
I write about tech on Zhihu and share travel photos on Instagram to document life outside the terminal. Feel free to email me for research discussions, collaborations, or whatever else.
