 emistry\, University of Cambridge

DESCRIPTION:The harnessing of solar energy to perform complex chemistries 
 sustainably and on a global scale has been mastered by nature over 3 billi
 on years ago with the emergence of photosynthesis. The ability to wire pho
 tosynthetic machineries to electrodes for photo-electrochemistry is a rela
 tively new approach for studying photosynthesis. Additionally\, this new a
 bility allows us to re-wire photosynthesis and create novel pathways for p
 erforming solar-energy conversion.(1\, 2) In a recent example\, our collab
 orators wired photosynthetic bacteria to electrodes power a micro-processo
 r for over a year.(3) \n\nIn the spirit of fostering new ideas and intra-d
 epartmental conversations\, my talk will be divided into three parts. Firs
 t\, I will give an overview of efforts in my lab to steal energy and elect
 rons from photosynthesis.(4-6) Second\, I will briefly discuss how the pla
 tforms being developed in my lab\, which aims to modify the bioenergetics 
 of cells\, can be applied to research questions beyond renewable energy ge
 neration. Lastly\, I will highlight some unfilled gaps within my field of 
 research that could benefit from collaborations within the department and 
 other disciplines.  \n\n\n\nReferences: \n\n1.         J. Z. Zhang\, E. Re
