Hongchen Wei

I am currently a second-year Ph.D. student in School of Remote Sensing and Information Engineering from Wuhan University, under the supervision of Prof. Zhenzhong Chen.

I received my M.E. degree in School of Computer Science and Engineering from Nanjing University of Science and Technology, China, in 2023.

I received my B.Sc. degree in School of Materials Science and Engineering from Xi'an Shiyou University, China, in 2020.
