Background
  • PhD candidate at UC San Diego, advised by Prof. Julian McAuley
  • Research interests: generative recommendation, action tokenization, and large language models (LLMs)
  • Focuses on building AI systems that learn from human actions to better understand and interact with people
  • Core research question: How should we represent human actions when building generative models?
  • Recent work includes: Action tokenization, generative recommendation, and LLM-based recommendation
