Dr. Xiaojing Gao is an Assistant Professor of Chemical Engineering from Stanford University. He received a B.S. in Biology from Peking University and a Ph.D. in Biology from Stanford University. He received his postdoctoral training from Biology and Biological Engineering at Caltech. His lab tackles fundamental engineering challenges across different levels of complexity, such as (1) protein components that minimize their crosstalk with human cells and immunogenicity, (2) biomolecular circuits that function robustly in different cells and are easy to deliver, (3) multicellular consortia that communicate through scalable channels, and (4) therapeutic modules that interface with physiological inputs/outputs. Their engineering targets include biomolecules, molecular circuits, viruses, and cells, and their approach combines quantitative experimental analysis with computational simulation. The molecular tools they build will be applied to diverse fields such as immunology, neurobiology, and cancer therapy.
