Geometric mechanics, control theory, mechanics of elastic structures, robotic manipulation

My research focuses on geometric control theory and its applications in mechanics and robotics.  Within control theory, I study symmetries in optimal control problems, specifically the effects of symmetries on sufficient conditions for optimality and on topological properties of families of solutions.  I then use these results from optimal control theory to formulate and analyze models of deformable objects.  I am particularly interested in the stability properties of thin and constrained elastic structures.  Finally, I use these models to derive methods for robotic manipulation of elastic objects, such as deformable cables and thin surfaces.
