About Me
I am a fifth-year Computer Science PhD student at Columbia University, advised by Prof. Changxi Zheng.
My research interests lie at the intersection of physical simulation, optimization and machine learning.
My research is supported by a Roblox Graduate Fellowship.
In my research, I develop numerical and machine learning techniques to
improve physical simulation, or conversely, use physical and geometric information to enhance
real-world 3D tasks.
Before coming to Columbia, I received my MSc in Computer Science from University of Toronto in 2021, advised by Prof. David I.W. Levin, and my B.Eng. in Computer Science and Technology from Zhejiang University in 2019.
✨✨ I'm on the industry job market in 2026. Feel free to
get in touch ! :)

How to pronounce my name?
My first name is pronounced as "Hong-Lin". "Hong" is pronounced the same way as the first half of "Hong Kong", and "Lin" is pronounced the same as "Lynn".
I am happy to accept any variation of the pronunciation of my name, so feel free to use your favorite approximation. :)
