Jiarong Hong is interested in developing novel flow imaging techniques aka flowscopes that allow us to “see” the flow and particle movement within the flow at unprecedented spatial and temporal resolutions across a broad range of disciplines. Using such flowscopes, his work not only addresses challenging fundamental questions in the field of fluid dynamics, but also enables research in other fields including oceanography, agriculture, robotics, microbiology, medical sciences, material sciences, etc.
