Hi! I am Yuchen Zhang, a researcher/engineer interested in Statistics, Causality, Natural Language Processing, and Machine Learning generally. I care deeply about science for social good and believe that our research in advanced technology and algorithms should benefit the public in a safe and fair way. Previously I worked at Meta as a Research Engineer on Trust and Safety, and some data/evaluations for Llama 2+ models and other models. I am currently interested in Agent Safety, Causality, and AI for Science.
