Jianjin Xu

I am a Ph.D. in Robotics student at Carnegie Mellon Univeristy working with Prof. Fernando. Before that, I obtained a master's degree at Columbia University working with Prof. Changxi Zheng, and a bachelor's degree at Tsinghua University working with Prof. Xiaolin Hu. I am also an alumnus of RDFZ graduated on 2015. My research interests include 3D human avatar generation, video diffusion models for humans, generative models, and 3D computer vision. Feel free to reach out to connect or collaborate!
