Research Overview

My research interest is in the design of new metallic materials by the chemical composition, the microstructure and the structure optimization.
I especially focus on:

Metallurgy, microstructure characterization and mechanical testing
Additive manufacturing process of metals and alloys
Modeling the microstructure evolution and the phases stability
Hot deformation processing and thermomechanical treatments
Finite elements modeling of lattice architectured materials
