A STUDENT OF NETWORKS & SYSTEMS

Doan Van Tai.

Research with curiosity.
Engineering with purpose.

I explore network digital twins, learning for networking, and the decisions that connect models to real systems.

01 / ABOUT

Between a question
and a working system.

I’m a final-year Computer Networks and Communications student at UIT, VNU-HCM, working toward a career as a Research Engineer. I explore how networks can be understood, optimized, and operated through digital twins, learning, and careful experimentation.

I’m especially interested in the gap between what a model predicts and what a network actually does. My projects bring together simulation, SDN testbeds, and reproducible evaluation to explore that gap.
