Studying how models learn from feedback and use tools:
LLM post-training, reinforcement learning, and agents.
MSc student at Tsinghua University, based in Shenzhen. I connect training and evaluation with multimodal learning and speech/audio processing.
My current work focuses on LLM post-training and tool-using agents: making learning signals inspectable, building useful interaction protocols, and evaluating failure modes.
I work through small, reproducible experiments before making larger claims. My public repositories include synthetic-data training studies, distributed gradient checks, learning implementations, and application prototypes.
Speech enhancement and microphone-array processing remain part of my research foundation. I am interested in how signal processing, representation learning, and distributed computation connect.
