SEB at Marseille 2008
Integrating the Mechanics and Energetics of Locomotion
Sponsored by the SEB Biomechanics Group
Organised by Richard L. Marsh,
Co-organizer David C. Ellerby, Wellesley College
The symposium will attempt to uncover the links between the mechanics and energetics of locomotion. We will have presentations on locomotion in fluid media (swimming and flying) and legged locomotion (walking and running). The participants represent a mix of established investigators and younger scientists.
