Welcome! I'm Junjie Chen

Ph.D. in Computer Science. at Tokyo

I am a research and engineer specialized in Natural Language Processing (NLP). I received my Ph.D. degree in Computer Science from the University of Tokyo in 2025, where I worked on unsueprvised syntax parsing with LLM. Then, I joined Amazon as a Science Fellow on a multimodal book translation. My main contribution is a multi-step multi-modal translation pipeline, in addition to my work at the human/automatic evaluation.

I am interested in multiagent system and large-scale knowledge base.
