Welcome to Jimmy's homepage
I am Jieming Li, an undergraduate student in Computer Science and Technology at Tsinghua University. I currently conduct research with Prof. Mengdi Xu at the Institute for Interdisciplinary Information Sciences, focusing on world models and vision-language-action models.
My research explores how embodied agents can learn from experience, anticipate the consequences of their actions, and recover intelligently from failure. I am particularly interested in connecting generative world modeling with reliable robot decision-making.
