About me

I'm Zoey (Zhiyu) Chen, and I am a Research Scientist at Meta (Facebook) Reality Labs. Before that, I obtained my PhD in Computer Science at the University of California, Santa Barbara. I was advised by Prof. William Wang and Prof. Xifeng Yan.

I'm broadly interested in natural language processing and deep learning. Specifically, I have been working on building the AI models that can ground on knowledge sources and make interactions with the users, which covers the areas of dialogue and interaction systems, question answering, natural language generation, and knowledge reasoning.

Fun Stuff

Reading and Writing.

I am passionate about psychology and philosophy, and enjoy reading - big fan of Nietzsche and Camus! I also like writing micro novels in my spare time, check my Zhihu (in Chinese) for my stories and thoughts.

Art and Design.

Art and design - also a huge part of my life. I like sketching, photography, video clipping, designing micro movies. Check out some of my sketchs and photos on Instagram and 500px. I was the head of the propaganda center of the student union during my undergraduate. I was the co-organizer of the welcome party of my college, and the director/co-director of over 10 micro movies and promotional videos. Check some of them (in Chinese) Here.
