Zihao Li

I am currently Doctoral Researcher in the Language Technology Group at University of Helsinki, supervised by Prof. Jörg Tiedemann, and co-advised by Dr. Shaoxiong Ji from Technical University of Darmstadt.

I received my Master’s degree in Data Science from the University of Helsinki and my Bachelor's degree in Computer Science from Northeastern University, China.

I am interested in Multilingual NLP, Large Language Model, and Machine Translation. My current research focuses on expanding the multilingual capabilities of LLM.
