Our group uses experiments, analytical theory, and computer simulations to explore the processing-structure-property relationships in structural metals and materials, with particular emphasis on the role of structural disorder and its effect on mechanical properties. Our research covers many length scales, from long-range disorder in grain boundary networks, to the nanoscale disorder in amorphous and nanocrystalline alloys.
Nanocrystalline metals are highly defected structures that accelerate sintering. We study the kinetic competition between low-temperature densification and organic removal and develop a grain size dependent map, which allows to predict the sintering behavior of a broad range of materials.

Grain boundaries contain a broad range of segregation sites. We have estimated distributions of grain boundary segregation entropy, and found a correlation between site-wise segregation energy and entropy. The spectra along with a spectral thermodynamic model shall provide an insight into extracting segregation entropy from experiments.
