Biography

In my lab, we seek to understand how biological movements, like those seen during feeding and locomotion arise from mechanical interactions between contracting muscles, springy tendons and jointed skeletons. We combine tools from biomechanics, functional morphology and muscle physiology in a program of relevance for students interested in organismal biology, ecology and evolution, or biomedical and health-care careers. Our current projects aim to determine how changes in movement patterns impact ecological transitions and we also study how muscle-tendon mechanics change through the life of organisms, with direct implications for questions in human health.
