Biography

Marco L. Bittencourt has a PhD in mechanical engineering at the University of Campinas in Brazil. He was a post-doc at the University of Kentucky and a visiting professor at the Division of Applied Mathematics at Brown University. His main research area is computational mechanics with emphasis on non-linear structural mechanics, high-order finite elements, and high-performance computing applied to the design of engine components and more recently biomechanics.
