Hi! I’m currently a Direct PhD student at ETH Zurich, supervised by Prof. Andreas Krause. I am deeply passionate about developing AI solutions that are beneficial to society and align with human values. I previously graduated from The University of Hong Kong, and I also spent some time at UC Berkeley (Center for Human-Compatible AI), Stanford University and Columbia University prior to ETH. You can call me Cynthia or Chen Xin (陈欣). My current research interests span across:
I am grateful to be supported by the Open Phil AI Fellowship and the Vitalik Buterin PhD Fellowship for my research.
To help with growing the AI alignment research field, I am among the main organizers of SafeAI workshop at AAAI and AISafety workshop at IJCAI. The best way to reach me is through my email xin.chen@inf.ethz.ch.

Oct 2023: I helped facilitate the first International Dialogues on AI Safety at Ditchley Park, Oxford with Profs. Yoshua Bengio, Andrew Yao, Stuart Russell, and Ya-Qin Zhang. We published a statement here. I am honored to have authored the Chinese statement.
Nov 2023: Open Problems and Fundamental Limitations of Reinforcement Learning from Human Feedback got accepted to TMLR! Many thanks to Casper for leading the effort.
Dec 2023: I will be at the Alignment Workshop and at NeurIPS. We are also organizing the Socially Responsible Language Modelling Research Workshop on Dec 16. Come find us at SoLaR, or feel free to shoot me an email if you’re interested in chatting.
