I am a final-year Ph.D. student in the Department of Computer Science and Engineering at the University of California San Diego (UCSD), working with Prof. Arya Mazumdar.
During my Ph.D., I have interned at AWS Agentic AI, Google Research, and RIKEN AIP.
Research
My research aims to build AI systems that learn efficiently and generalize reliably.
I pursue this goal by developing better learning algorithms, establishing their theoretical foundations, and studying how models acquire and transfer knowledge. My current focus is LLM post-training for reasoning models and agents.
LLM Post-training & Agent Learning
I develop reinforcement learning and on-policy distillation methods that help reasoning models and agents learn more effectively from teacher supervision and task feedback. My work aligns token-level learning signals with task rewards, connects distillation to RL advantage estimation, and uses privileged training information to improve agent learning.
I study how data, optimization, and model structure determine learning efficiency and generalization. My work develops generalization bounds through connections between training trajectories and kernel methods, analyzes transformer in-context learning, and establishes guarantees for dataset distillation using compact synthetic datasets.
I investigate what knowledge neural networks acquire and how it is represented and transferred across models and tasks. My work studies relationships between fine-tuned representations, improves automated neuron explanations, and quantifies concepts learned through distillation.
