About
Ryan Behunin explores the physics of fluctuation-induced phenomena (FIP), optomechanics, and quantum systems. His work on FIP investigates fundamental questions regarding the interaction of light, sound, and matter—spanning from quantum friction to laser noise. Within the field of optomechanics, Ryan is currently focused on Brillouin physics, describing the interaction of light and sound. By using unique aspects of Brillouin physics, Ryan and collaborators have developed new high-performance chip-scale lasers, precision sensors, and novel methods of laser cooling.
