About

"Efficiency isn't about doing less — it's about understanding more."

Hi! My name is Junhan Zhu (诸俊涵). I am a 3rd year undergraduate student at Westlake University, majoring in Electrical and Information Engineering. My research interests include Computer Vision, Generative AI, and Efficient AI, especially in the area of model compression and acceleration.
I will share my research and personal thoughts on my blog, "Lonely Zone". Check it out here for my latest updates and thoughts! [Lonely Zone]
I am deeply grateful for the guidance and support I have received from my mentors, senior students, and friends.
I am always open to collaborations and discussions. Please feel free to contact me at zhujunhan@westlake.edu.cn.

I am actively seeking 27 Fall PhD opportunities!
