About

Song Chang is a leading figure in the biomechanics of insect flight, whose work has fundamentally reshaped our understanding of how tiny creatures conquer the air. His research centers on the sensory-motor control and aerodynamic stability of flapping-wing flight, bridging the gap between biological observation and physical theory. In his highly influential 2013 paper, cited over 169 times, Chang developed a groundbreaking theory that predicts the intrinsic pitch instability of flying insects from basic flapping-wing aerodynamics. He then demonstrated that insects employ a dual strategy for stabilization: a passive, aerodynamic damping mechanism inherent in their wing motion, and an active, neural feedback system that corrects for disturbances. This dual-framework has become a cornerstone for biologists studying insect evolution and for engineers designing bio-inspired micro-aerial vehicles. By elegantly explaining how a fly or moth stays upright despite chaotic airflows, Chang has provided a foundational model for stability in all flapping flight, earning him recognition as a key innovator at the intersection of physics and biology.
