My research field is in integrated circuitry. In particular, I undertake interdisciplinary research on biological information processing and integrated-circuit technology.

I have developed a neuromorphic visual information processing analog VLSIs known as “silicon retina”, a high sensitivity CMOS bio photo sensor for bioluminescent detection and a multi-channel current stimulator for artificial vision. Presently, I focus on research and development of multi-channel measurement and stimulation devices for implantable brain-machine-interface (BMI) system.
