Hi, I am Dian Jin (金典), a third-year PhD student in Electrical and Computer Engineering at UW-Madison, advised by Prof. Jeremy Coulson. My main research interests include learning-based control, optimization on manifolds. In 2022 I received my Bachelor’s degree in Mathematics from Soochow University. I received my Master’s degree in Mathematics from UW-Madison in 2023. Beyond research, I am passionate about photography and outdoor exploration.
