Hi! Sophia / 孙慧文 here.
I currently work at perplexity on agentic AI. I got my PhD in Computer Science at UC San Diego, advised by professor Rose Yu, with a thesis on probabilistic machine learning, uncertainty quantification, and decision making under uncertainty.
I'm also interested in machine creativity and digital humanities. My band the SEALs makes music with DIY electronics and AI systems; I make robots to explore the relationship between human, nature, and machines.
