• Matter-antimatter asymmetry problem studies using e+e- collision data.

The Belle and the Belle II experiments. Currently, our group analyzes the Belle (II) data for physics analysis and the trigger work. Below picture is a prototype 3-D chamber and trigger electronics that our group constructed.

• Understanding physics of very early universe from the observation of the Cosmic Microwave Background. 

The GroundBIRD experiment. We are commissioning the main telescope and developing an IR camera for the cloud monitoring. See below picture.
