Song Hu’s research focuses on the development of cutting-edge optical and photoacoustic technologies for high-resolution structural, functional, metabolic and molecular imaging in vivo and their applications in neurovascular disorders, cardiovascular diseases, regenerative medicine, and cancer. In particular, his lab has invented multi-parametric photoacoustic microscopy, which enables simultaneous imaging of blood perfusion, oxygenation and flow at the microscopic level and lays the technical foundation for high-resolution oxygen-metabolic imaging.
