Fu obtained his B.S. in Math and Physics from Tsinghua University, and his Ph.D. in Chemistry at Harvard University. His graduate work focused on the development of syringe-injectable mesh electronics for long-term brain electrophysiology. During his postdoctoral training at HHMI Janelia, he developed a multimodal optical scope with adaptive imaging correction (MOSAIC) for 4D high resolution imaging of subcellular dynamics inside multicellular organisms. His work has been selected as a Top 10 World Changing Idea by Scientific American and one of the Most Notable Research Advances of the Year by Chemical & Engineering News.
