About me

Lifu Tu is a research scientist at Salesforce AI Research. He earned his Ph.D. from TTI-Chicago, a philanthropically endowed academic computer science institute located on the University of Chicago campus. During PhD, I was advised by Kevin Gimpel.

His current research encompasses multilingual and multimodal generation, retrieval-augmented generation (RAG), and methods to enhance factual consistency in large language model outputs. Beyond language, he explores cross-modal innovation—most notably text-to‑video synthesis (as demonstrated in the xGen‑VideoSyn‑1 model) — and structured prediction techniques for richer, more reliable generation systems.
