We work on the development of biologically inspired catalysts and their application to energy conversion and production systems. Specifically, we attempt to exploit the nature’s ingenuities of multielectron catalytic reaction, electron/proton transport, metabolic regulation, flexible response to external stimuli, and the robust energy management in a deep sea environment to develop the novel materials and systems necessary for the effective management of renewable energy sources.


  1. Development of water oxidation catalysts inspired by PSII center in natural photosynthesis
  2. Electricity production using the microbial ability of extracellular electron transfer
  3. Investigation of giant electroecosystems in a deep hydrothermal environment
Electron Flow & Evolution of Life
Our target is to find the role of electrical current for emergence and evolution of life; how nature has utilized the electrical current from billion years ago, and its relevance in our modem technology, such as fuel cell, battery, voltage amplifier, and thermoelectric conversion. Knowing the evolution of this in nature would be a nice guidance to realize sustainable human ecosystems.
