About me

Hello! I’m Zhimeng, a PhD student at Georgia Institute of Technology. My research interests lie in theoretical computer science, with a focus on online algorithms and computational geometry.

I received my bachelor’s degree in Computer Science and Mathematics from Hong Kong University of Science and Technology, where I was lucky to be advised by Siu-Wing Cheng for my final year thesis. I spent an exchange semester at UIUC in Spring 2023, during which I worked with wonderful mentor Sariel Har-Peled. Prior to these, I interned at Google during the summers of 2021, 2022, and 2023.
