Guosong Zeng received Ph.D degree in Mechanical Engineering from Lehigh University in January 2018. His PhD research included investigation of mechanical properties of wide bandgap semiconductor materials, mechanochemistry mechanism of semiconductor thin films, as well as mechanochemical tunning of the band structure at the semiconductor surface. Then he joined Lawrence Berkeley National Laboratory as a postdoc. His postdoc work centered synthesis and characterization of photoelectrodes for solar water splitting and CO2 reduction. His work has been published on several high impact journals, including Nature Materials, Nature Energy, Angew, Advanced Energy Materials, PNAS, etc.
