Hi there, I’m an incoming PhD in Computer Science at NYU Shanghai, advised by Dr. Yucheng Lu. Prior to that, I completed my undergrad studies at NYU Shanghai from 2022 to 2026. Before that, I spent 6 years at Suzhou High School of Jiangsu Province (江苏省苏州中学).

My research interest lies in Deep Learning, Machine Learning Systems, and Reinforcement Learning. I was very fortunate to work with Dr. Zhuang Liu and Dr. Hao Peng during my undergrad studies. If you want to contact me, feel free to reach out by my email!
