About me

I am a researcher with Shanghai AI Laboratory, working in a research group on Content Generation and Digitization. I received my Ph.D. (2018-2022) from Multimedia Laboratory (MMLab) at CUHK, advised by Prof.Dahua Lin. I obtained my Bachelor's Degree (2014-2018) at Xi'an Jiaotong University.
My current research focuses on 3D content generation, including 3D object and scene generation. I am looking for highly motivated interns in 3D generative models at Shanghai AI Laboratory. Drop me an email (lvzhaoyang@pjlab.org.cn) if you are interested.
