Zhu Liu 刘铸

I am Zhu Liu, a third-year Ph.D. student in the School of Software at Dalian University of Technology (DLUT), specializing in Software Engineering under the supervision of Professor Risheng Liu. My research focuses on bi-level optimization, multi-spectral image processing and fusion.

Bi-level optimization serves as an efficient tool for modeling complex coupled learning problems. Concurrently, multimodal image processing and fusion offer an efficient pathway for achieving intelligent perception in unmanned systems, leveraging diverse sensor information to enhance perceptual capabilities. Against this backdrop, my research aims to design efficient bi-level optimization algorithms tailored for vision tasks. The goal is to achieve panoramic understanding and precise perception of real-world scenarios.

Before that, I received the B.E. and M.S.E degrees in software engineering at DLUT, China, in 2019 and 2022.
