About Me

I am a researcher at mercari R4D. I also works as a collaborative researcher in joint research project "Value Exchange Engineering" and xlab (Yasuaki Kakehi Lab.) at the University of Tokyo

I direct research and development of soft materials system based on advancements in shape-changing interface, soft sensor, soft robotics, mobility, and human computer interaction.

I am passionate about accelerating innovation and disruption through creating a soft materials system.

These projects are from collaborations during my time at different research labs, including the University of Tokyo, and Osaka Prefecture University.

Also, I have about 10 years of experience in the automotive industry and 5 years of management experience. I also have two times of experience setting up an organization and formulating an organizational strategy.
