Education
- PhD in Geological Sciences (mineralogy & crystallography) at Virginia Tech
Description of Research
Dr. Chakoumakos studies structure property relationships in technological and natural materials and the synthesis, crystal growth, and characterization of novel materials. He employs crystallography, mineralogy, and single-crystal and powder diffraction methods.
