There is now a CONTENT FREEZE for Mercury while we switch to a new platform. It began on Friday, March 10 at 6pm and will end on Wednesday, March 15 at noon. No new content can be created during this time, but all material in the system as of the beginning of the freeze will be migrated to the new platform, including users and groups. Functionally the new site is identical to the old one. webteam@gatech.edu

Abstract
The stiffness of propulsive appendages, such as feet and fins, is important in locomotory function. In this talk, I show that curvature-induced stiffness is the common principle underlying the stiffness of both primate feet and rayed fish fins. We use mathematical models, physical replicas, and biological experiments to arrive at this conclusion. The principle is evident in a drooping dollar bill that significantly stiffens upon slightly curling in the transverse direction.
Bio
Madhusudhan Venkadesan is an assistant professor in the Department of Mechanical Engineering and Materials Science at Yale University and studies the biomechanics and control of motor behavior in humans and other organisms. Problems being pursued include locomotion in animals, sun tracking in plants, and differential geometry of joints and nonequilibrium statistical mechanics of muscle. His lab also fabricates biologically inspired powered and passive devices to test the mathematical theories emanating from the biomechanical work. The motivation for—and application of—his work include biomedical sciences, evolutionary biology, robotics, and plain curiosity about everyday observations.
