The lab conducts networking research aimed at innovating the Internet.
AboutAbout the lab
Toward secure, high-speed networks
The Koizumi Lab aims to innovate the Internet and studies networking technologies that combine novelty with practicality.
The lab develops technologies for data center networks used to generate large-scale AI models, and for carrying out distributed machine learning securely and quickly.
It also works on security-related technologies such as cyberattack detection and anonymous communication, and, to implement these technologies inside the network, puts particular effort into programming ultra-high-speed network hardware.
On the lab's website, it is introduced as the Advanced Network Architecture Group, and it became the Koizumi Lab in February 2026.
