Associate Researcher@PCL

About me

My name is Zhuochen Fan (樊卓宸in Chinese). I graduated from Peking University (PKU) with a Ph.D. in Computer Science and continued my postdoctoral research there, both under the supervision of Prof. Tong Yang. Currently, I serve as an associate researcher (and also a doctoral supervisor) at Pengcheng Laboratory (PCL). My research covers various aspects of computer networks, ranging from measurement, storage, and security to architecture, as well as exploring their connections with Large Language Models.

我博士毕业于北京大学，并随后完成两年博士后研究；我目前是鹏城国家实验室（PCL）的副研究员、博士生导师（“PCL-中山大学”和“PCL-清华大学深圳研究生院”联培专项的PCL博导）；我的研究涵盖计算机网络的多个分支，如测量、存储、安全、架构，同时探索这些方向与大模型的深度融合。
