About me

Personal Info

Welcome to my homepage! My name is Lingwei Zhu (朱 令緯). I am now a Project Researcher at the CDR lab, University of Tokyo working with Prof. Yukie Nagai. Prior to coming to Tokyo, I spent two wonderful years at the RLAI Lab, University of Alberta as a postdoc working with Prof. Martha White. I obtained my PhD with the Best Student Honor at Nara Institute of Science and Technology (NAIST) under the supervision of Prof. Takamitsu Matsubara.

My research interest lies in applications of artificial intelligence and machine learning for solving complex real-world problems. Especially reinforcement learning and unsupervised learning for autonomous control of large-scale systems (industrial processes and robotics) and automated biomedical systems (cancers, brain activity cognition).
