Dr. Gao completed his Ph.D. in the Department of Mechanical and Aerospace Engineering at the Hong Kong University of Science and Technology in 2014. Since that time, he has been a Post-doctoral Researcher in Prof. Charlie Johnson’s group in the Nano/Bio Interface Center and Department of Physics and Astronomy at the University of Pennsylvania. At Penn, Dr. Gao developed a graphene sensor concept that enables detection of nucleic acid and antigen biomarkers for disease diagnosis at the early stage. He also invented a Ni-Cu gradient alloy catalytic system for manufacturable synthesis of crystalline multilayer graphene with a tunable energy bandgap for potential applications in high-resolution biosensing. In Oct 2019, Prof. Gao joined the Department of Biomedical Engineering at the Chinese University of Hong Kong as an Assistant Professor.
