Raag Airan is a bioengineer and assistant professor at Stanford University who bridges neuroscience, immunology, and fluid mechanics to develop innovative methods for treating brain disorders. His work is particularly focused on harnessing the brain’s natural clearance systems—like lymphatic drainage and microglial function—to remove harmful substances and improve recovery after injuries such as stroke. Blending cutting-edge technology with biological insight, Airan’s research aims to create noninvasive therapies, including the use of pulsed ultrasound, to modulate immune cells and boost the brain’s waste removal mechanisms.
