LLM Post-training: Reinforcement Learning and Distillation
Ph.D. candidate · UC San Diego
I am a final-year Ph.D. candidate in Computer Science and Engineering Department at University of California San Diego (UCSD) working with Prof. Arya Mazumdar. I received my M.S. degree from UCSD and B.E. degree from Xi’an Jiaotong University. During my Ph.D., I haved interned at AWS Agentic AI, Google Research, and RIKEN AIP.
I’m looking for full-time Research Scientist, Research Engineer, or Member of Technical Staff roles in LLM training, reinforcement learning, and AI agents. If your team is hiring, I’d love to connect!
I develop algorithms for LLM post-training, focusing on reinforcement learning and on-policy distillation for reasoning models and coding agents. My research combines algorithm design and theoretical analysis with distributed LLM training and empirical evaluation. Recent work includes Reward-Aligned Distillation and agent self-distillation using privileged information.
My broader research spans machine learning theory, including transformer in-context learning, provable dataset distillation, neural-network generalization, and connections between neural networks and kernel methods.
Feel free to drop me an email if you would like to collaborate or have a discussion!
