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 to effectively manage renewable energy sources.
