Youwei Lyu 吕游伟

I am currently a Researcher in vivo BlueImage Lab, where we develop frontier technologies (MLLMs, AIGC, etc.) to advance the quality and aesthetics of mobile photography. Before joining vivo, I received my Ph.D. from Beijing University of Posts and Telecommunications (BUPT), in 2025, advised by Prof. Boxin Shi. I obtained my B.E. degree from BUPT in 2019.

We are looking for self-motivated interns. If you are passionate about computational photography or interested in cutting-edge technologies (generative model, MLLMs, etc.), feel free to drop me an email.
