Samrat Choudhury’s expertise is in computational materials science. In the past, he has used a series of specialized computational techniques (ab-initio, cluster expansion, kinetic Monte Carlo, rate theory and phase-field) ranging from atomistic to continuum scale to study the role of defects such as grain boundaries, dislocations, surfaces, interfaces and point defects on functional and structural properties of ceramics and alloys. Some of these researches were performed in collaboration with researchers from industries (like INTEL and Samsung), national labs in the US (ORNL, LANL, PNNL, ANL) and universities. Choudhury’s past research findings have been published in Nature, Nature Materials, PNAS, Nature Nanotechnology, Advanced Functional Materials, Scientific Reports and other high impact journals. His authored/coauthored articles have so far garnered more than 2400 citations; h-index 21 (source: Google Scholar).
Choudhury’s research interest is in computational design of advanced materials with a primary focus on materials for various energy applications ranging from structural materials for nuclear reactors to novel materials for battery electrodes. In particular, he is interested in developing atomistic-informed phase-field model in order to link microstructure and materials properties at continuum scale with minimal experimental inputs. His research interest can broadly classified in to following categories.
