School of Physics Assistant Professor Simon Sponberg has the coveted cover story in the September issue of Physics Today. Sponberg, principal investigator in the Agile Systems Lab, gives a state-of-the-science report on animal locomotion; how different physiological systems within a moth, for example, interact within the insect to enable movement, and how that moth interacts with its environment. Data arising from new studies of such neuromechanics have applications for robotics. Sponberg is also an assistant professor in the School of Biological Sciences and an adjunct assistant professor in the Wallace H. Coulter Department of Biomedical Engineering.
