Research Interests

Professor Ahn鈥檚 research focuses on the neural control and mechanics of animal locomotion. We take an integrative and multi-disciplinary approach to examine the different levels of organization that influence the behavioral output of the neuro-musculo-skeletal system in animals such as frogs, lizards, tarantulas, and even humans! Our work includes examining the neural signals sent to muscles and how the different levels of musculo-skeletal organization respond to these neural signals. By spanning the fields of muscle physiology, biomechanics, and motor control, we hope to discover general principles underlying the neuro-mechanical basis of legged locomotion.
