Qiwei Du is a Ph.D. student at the Department of Computer Science and Engineering (CSE), University at Buffalo (UB). His research interests lie at the intersection of Neuro-Symbolic AI, robotic task and motion planning, and 3D computer vision, with a particular focus on building scalable, interpretable systems that bridge symbolic reasoning and neural perception. He has received a Presidential Fellowship. He received the SAIR Rising STAR Award 2025, which was the highest honor for junior researchers in SAIR Lab.
