If people do not believe that mathematics is simple,  it is only because they do not realize how complicated life is.

During my PhD, I got experience working on parallel manipulators and their geometric design. For more information about applications and prototypes, visit IRI's Laboratory of Parallel Robots. Visit the Thesis section for a summary of my PhD. Now you can download my thesis here!

My first postdoc, at the GrabLab, Yale University, I applied my knowledge about parallel robots to the kinetostatics of hands holding objects with precision grasps, that have similar structure to a parallel manipulator. For hands, the legs are the fingers and the platform the object being manipulated.

During my postdoc at the High Perfomance Humanoid Technologies Lab (H2T), I worked on several approaches to transfer properties of grasping to whole-body support poses using multi-contacts, that share similar structure than a hand holding an object, in this case, the hand is the robot and the object is the environment. I also worked on innovative gripper designs.

My research interest are in Geometry and Kinematics with applications to parallel robots, hand kinematics, grasping/manipulation and whole-body motions.
