About Me

I am a CIS PhD student at the University of Pennsylvania. I am conducting research under the supervision of Prof. Kostas Daniilidis and cooperating with other faculty. I obtained my master’s degree in robotics from UPenn. I graduated from Zhejiang University CS major in 2023 and participated in several research projects of Prof. Xiaowei Zhou. Then before that, I graduated from Hangzhou No.2 High School in 2019.
