Naresh C Osti

Naresh C Osti is a Neutron Scattering Scientist at Oak Ridge National Laboratory (ORNL), working as an R&D Staff/Beamline Scientist at the Backscattering Silicon Spectrometer (BASIS) within the Neutron Scattering Division. He is part of the Chemical Spectroscopy Group under the Spectroscopy Section of the Neutron Scattering Division, which falls under the broader Neutron Sciences Directorate at ORNL.

Dr. Osti received his MS in Physical Chemistry from Tribhuvan University, Kathmandu, Nepal, and his PhD in Chemistry from Clemson University, Clemson, SC, USA, in 2014. After completing his PhD, he joined ORNL as a postdoctoral researcher, working under the supervision of Dr. Eugene Mamontov until 2017, when he transitioned to his current R&D Staff position.

His research focuses on exploring the structure and dynamics of energy-related materials (both hard and soft) to understand their structure-property relationships for real-world applications, especially in the areas of nano-confined fluids, polymers, and polymer nanocomposites. His work heavily utilizes neutron scattering techniques to investigate molecular dynamics and structural properties of advanced materials.

Dr. Osti's recent publications demonstrate expertise across multiple domains including solid-state battery materials, polymer nanocomposites, ion transport phenomena, and advanced neutron scattering methodologies. His work spans fundamental understanding of molecular dynamics to practical applications in energy storage technologies.
