Zhengqiang ZHANG (郑强 张)
I am currently a fourth-year PhD student in the Department of COMP at Hong Kong Polytechnic University (PolyU), supervised by Prof. Lei ZHANG. Prior to that, I worked as Multimedia AI Algorithm Engineer at HUYA Company for about one half and one year. I received my Master’s (supervised by Prof. Xinge You) and Bachelor’s degree at Huazhong University of Science and Technology (HUST). My research interests lie in image generation and image reconstrcution. Recently, I focus on diffusion generative models.
