Research focus

My research interests are in computational mechanics, finite element analysis and multiscale material modeling. I primarily focus on the development of image-through-analysis tools for the simulation of multiphysics and multiscale mechanical systems. The main application driving my work is strength and stability assessment of cereal crops with the goal of possibly breeding lodging resistant crops.
