I am a second-year PhD student at Language Technology Lab, University of Cambridge, advised by Prof. Anna Korhonen. My legal name is Yijie and Ej is preferred phonetic approximation.
My PhD is focused on Natural Language Processing and especially multilingual interpretability of large language models.
Before this, I did my Bachelor in Computer Science and Engineering from Zhejiang University, also member of the Chu Kochen Honors College. During my undergrad I am grateful to be advised by Prof. Yue Zhang as research intern at Westlake University. I spent one semester as an exchange student in Cornell University, where I worked as a research assistant in CommCollabTech.
I also did a research internship in Yale University under the supervision of Prof. Arman Cohan.
I was a visiting student at University of Oxford for the final year of my undergrad.
