Research Focus

Dr. Ghamarian's research focuses on establishing methods for tuning structural materials by understanding the relationships between processing, microstructure, and properties. For this purpose, Dr. Ghamarian uses extensive coupling of four activities which are

3D printing of materials by various additive manufacturing methods
data analytics to shed light on the information which is laborious to capture
advanced characterization using different electron microscopes
computation at different length scales to correlate the characterization and mechanical property results to their governing mechanisms.

The overall output of his research is expediting cost-efficient materials development following Materials Genome Initiative goals. For more information on Dr. Ghamarian's research, please visit the Accelerated Materials Development Lab (AMDL) website.
