Biography

Arun Devaraj is a materials scientist in the Physical and Computational Sciences Directorate at PNNL. His research focus is microstructure-property relationships of metallic alloys, oxides, and composite materials. Dr. Devaraj has extensive experience in applying atom probe tomography (APT) for material characterization, in addition to scanning electron microscopy, energy dispersive X-ray spectroscopy, focused ion beam, transmission electron microscopy (TEM), X-ray absorption near edge spectroscopy, scanning transmission X-ray microscopy and in-situ high energy X-ray diffraction at beamlines in various U.S. Department of Energy synchrotron facilities.

Specifically, Devaraj is interested in microstructure evolution in metallic alloys used in various structural applications, ranging from automotive applications, nuclear materials, and other energy related applications. He is also focused on nanoscale characterization of lithium/sodium (Li/Na) ion battery materials, catalysts, and high strength natural biomaterials.
