Yuhan Lin earned a bachelor’s degree in biology from Peking University, where they worked in Xiang Yu’s laboratory on the development of neural circuits. She is now a first-year graduate student at Peking University, working in Xitong Liang’s laboratory on the neural computation underlying cuttlefish behaviour, particularly visual information processing and camouflage. Yuhan is interested in the functional logic of neural circuits and hopes to strengthen their computational modelling and data-analysis skills through the course.
