About Yumo Xu
I am an LLM researcher at Netflix. My overarching research goal is to build helpful and responsible AI systems to improve how people access information and take actions. My research centers on post-training foundation models to instill advanced reasoning and improve alignment. I am also interested in extending these capabilities to multi-modal domains and creating evaluations that meaningfully reflect their real-world utility.Prior to Netflix, I was a scientist at AWS AI Labs. I received my PhD in NLP at the University of Edinburgh, advised by Prof. Mirella Lapata.
