# Marko Knezevic, Assistant Professor

## Credentials

Prof. Knezevic joined the faculty of the Mechanical Engineering Department in spring semester 2013. Prior to joining the department, he worked at Scientific Forming Technologies Corporation in Columbus, OH from 2009 to 2011 as a principal research scientist for development of the commercial finite-element software DEFORM used for analysis of manufacturing processes. After industrial experience, he was with the Materials Science and Technology Division at Los Alamos National Laboratory in Los Alamos, NM from 2011 to 2013 as the LANL Seaborg Institute Postdoctoral Fellow.

Prof. Knezevic’s research is focused on understanding of materials behavior under complex loading using a combination of computational methods and experiments, development of constitutive material models, design and manufacturing at component levels, materials design at microstructural length scales, as well as the development of high-performance computational applications integrating multi-scale material models for predicting materials behavior.

Prof. Knezevic teaches ME 643 - Machine Design, ME 922 – Continuum Mechanics, and ME 995 - Computational Mechanics of Materials.
