About

Zhangkai NI is an Assistant Professor of Computer Science and Technology at the Tongji University. He obtained his Ph.D. degree (Oct. 2021) in Computer Science from the City University of Hong Kong under the supervision of Prof. Sam Tak Wu KWONG (IEEE Fellow). Over the years, he was lucky to have some amazing collaborators who have helped me along the way. He was fortunate enough to work closely with Prof. Kai-Kuang MA (IEEE Life Fellow), Prof. Hanli WANG, Dr. Shiqi WANG, Dr. Lin Ma, Prof. Huanqiang ZENG, and Dr. Wenhan YANG.

His research interests include computer vision, computational photography, and image processing, particularly generative modeling, unsupervised learning, neural rendering, image/video restoration, image/video enhancement, and image/video quality assessment.

I am looking for self-motivated students (masters and undergraduates), working together on projects related to image processing, computer vision and machine learning. If you are interested in working with me, please send me an email with your resume (zkni@tongji.edu.cn).
