I am Zongji Yu. I received my B.Eng. in Robotics Engineering from the School of Control Science and Engineering, Shandong University (SDU), where my graduation project was recognized as an Outstanding Undergraduate Graduation Project of Shandong University.
I am currently a Ph.D. student at the School of Automation and Perception, Shanghai Jiao Tong University (SJTU), advised by Professor Chen Gong in the LEAP Group. My research focuses on Continual Learning and Evolving AI.
I am also a research intern at Shanghai AI Laboratory, under the mentorship of Young Scientist Chaochao Lu. My work there focuses on Intrinsic AI Safety: developing AI systems with safety capabilities that arise from within their learning and reasoning processes.
My broader research goal is to build learning systems that adapt continuously, evolve responsibly, and remain safe in open-ended environments.
