Biography

Wahyu Setyawan has a background in engineering, experiment, and computation. His interest in materials science is broad. He has expertise in computational materials science using density functional theory method, molecular dynamics and Monte Carlo simulations, development of interatomic potentials, machine learning analysis, and development of high-throughput computational tools. Since joining PNNL in 2011, he has been active in developing materials for fusion energy devices and in understanding neutron irradiation effects on the properties of the materials. Current research includes development of ductile-phase toughened tungsten composites and ductile refractory multiple principal component alloys for use as materials for plasma-facing components, simulations of atomic displacement cascades in tungsten and iron-chromium ferritic steels, and silicon carbides, development of machine learning interatomic potential to understanding He and H effects in irradiation damage accumulation in nanostructured ferritic alloys (NFAs), development of oxide-dispersion strengthened (ODS) steel plates, characterization of defect microstructures in ferritic steels and NFAs, and simulations of tritium permeation through palladium-coated vanadium vacuum permeator membrane. He also has experience in experimental work in powder metallurgy, nanostructure self-assembly, dippen nanolithography, photolithography, fabrication of biosensors, atomic force microscopy, scanning tunneling microscopy, x-ray diffraction analysis, and vacuum systems. He is a co-author of the AFLOW and ACONVASP high-throughput ab initio softwares. He contributes band structure calculations of > 10,000 inorganic compounds.
