Computational Modeling of Materials

Advances in computing power and software offer the potential to design, synthesize, characterize and test materials in a virtual setting. These capabilities enable accelerated development and optimization of new materials across a range of applications. The Department's long-term investment in this vision has produced one of the leading programs in computational materials science and engineering. This is evidenced by:

  • A large core facility offering comprehensive coverage of advanced techniques
  • Access to world-class computing facilities, including the Ohio Supercomputing Center
  • A rich experimental environment to motivate and challenge computational research
  • Graduate core and elective courses in computational modeling and simulation
