About

Elizabeth Brainerd is a leading figure in comparative biomechanics and functional morphology, whose work illuminates the remarkable ways animals move and feed. Her research focuses on the mechanics of feeding, locomotion, and fluid dynamics in vertebrates, with a particular emphasis on how soft tissues and skeletal structures interact to produce complex behaviors. One of her most celebrated contributions is the discovery of the "hemodynamic nectar mop" mechanism in the bat *Glossophaga soricina* (2013, 81 citations), where she demonstrated that the bat uses dynamic, erectile papillae on its tongue—powered by blood flow—to rapidly and efficiently collect nectar, a finding that reshaped our understanding of convergent evolution in nectarivores. Beyond this, Brainerd has pioneered the use of X-ray Reconstruction of Moving Morphology (XROMM), a groundbreaking imaging technique that allows scientists to visualize internal skeletal movement in 3D during live animal motion. Her work has garnered widespread recognition, including a Guggenheim Fellowship, and continues to inspire students and researchers in evolutionary biology and bioengineering.
