Photonic Computing and Network
We aim for high-performance computation by utilizing photonic approximate computing. We make the best use of optoelectronic integration technology to propose a new system architecture.
-
Uncertainty-Tolerate Computing
We aim to enhance the performance of data centers utilizing optical communication while tolerating computational inaccuracies.
-
Security of Computer Systems
To realize Society 5.0, semiconductor chips with zero-trust security are essential. We aim to find a new security risk of a hardware Trojan for eavesdropping and reducing the system performance and present its countermeasure.

In-Water Computer
Cooling the chips has become a challenge. We are exploring direct immersion cooling using tap water. The computer is coated with a parylene film and cooled in water. Submersion cooling offers excellent heat transfer rates and is easy to handle, but there are challenges related to durability and component replacement.
