Zirui's Homepage
About me
I’m Zirui “Ray” Liu, an assistant professor from the Department of Computer Science at UMN. Previously I graduated from Computer Science at Rice University.
I am mostly interested in Large Language Models and their applications, focusing on enabling them to combine and process information from diverse sources and domains. For that reason I deeply care about efficiency, reasoning, long-context ability, and understanding their inner working mechanism. I also enjoy extending foundation models to other domains, exploring the interplay between different source of data.
📧📧 Recruiting 2025 Fall Ph.D. students and interns: I am always looking for self-motivated students with strong coding skills. Feel free to drop me a line to ziruiliu dot recruit at gmail dot com together with resume, transcripts, and a short description of why you’d like to work with me.
