Graduate PhD Students:
 Fernando Dri


Dr. Fernando Dri, Ph.D. Dec. 2013  [Personal Web Page]
fdri@purdue.edu
PhD thesis title:  Multiscale Modeling of Hierarchical Structure of Cellulose Nanocrystals (CNCs) materials

Currently
:  Dassault Systèmes , Vélizy-Villacoublay, France.

Bio: Fernando Dri  obtained his degree in Aeronautical Engineering at the Universidad Nacional de La Plata (UNLP) in Argentina in 2009. He joined Prof. Zavattieri's group in Aug. 2010. Fernando  is currently conducting research on the development of a multiscale framework that can be used to describe and predict the cellulose nanocrystals mechanical behavior and connect atomistically informed models to experiments using continuum-based modeling techniques. In his work, Fernando uses elements of solid mechanics and computational mechanics to advance our fundamental knowledge of the individual and collective structural response of molecular cellulose chains and particles while improving our understanding of cellulose as a fundamental building block for the design of green and sustainable materials.
