Dr. Shetty is a materials and mechanical engineer with expertise in advanced characterization of material failure in extreme environments. He has worked on components ranging from the small scale (2D materials) to the very large (refinery pipelines). His previous work includes the development of layered semiconductors, novel memory devices, corrosion and oxidation resistant alloys, ultralow-temperature batteries, and solid-state batteries. His research generates understanding on how challenging environments like corrosive fluids, extreme temperatures, radiation, and electrical bias induce material transformations. He uses a variety of ex/in situ and operando characterization techniques to understand how surfaces, interfaces, structure, chemistry, and the strength of materials evolve in operating conditions.

Dr. Shetty has extensive experience in characterizing materials for electronic devices and energy generation/storage using atomic force microscopy (AFM), x-ray photoelectron spectroscopy (XPS), optical microscopy and profilometry, scanning electron microscopy (SEM), focused ion beam (FIB), energy dispersive x-ray spectroscopy (EDS), x-ray diffraction (XRD), nanoindentation, and transmission electron microscopy (TEM/STEM). Additionally, he has designed custom experiments in optical microscopes, SEM, and TEM to observe material transformations as they occur and correlate this information across length-scales.

Prior to joining Exponent, Dr. Shetty was a Postdoctoral Fellow at Georgia Institute of Technology where he developed in situ and low dose imaging techniques to improve the characterization of 2D semiconductors and alkali metal batteries. Before working at Georgia Tech, he was a Graduate Research Assistant at University of Illinois at Urbana-Champaign where he developed corrosion resistant thin films and bulk metallic parts using microstructural and compositional control.
