Raj Koju

Raj Koju is a Postdoctoral Fellow at the Physics & Astronomy Department of George Mason University, affiliated as Research Faculty. His work focuses on computational modeling of materials' mechanical and kinetic properties using molecular dynamics and Monte Carlo methods. He holds a Ph.D. (2019) and M.Sc. (2011) in Physics from George Mason University and Tribhuvan University, respectively.

His research interests include atomistic simulations of nanocrystalline alloys (e.g., Cu-Ta, Al-Mg), diffusion processes at interphase boundaries, and mechanical behavior under extreme conditions. Notable projects involve investigating thermal stability of Cu-Ta alloys, solute drag effects in Cu-Ag alloys, and grain boundary dynamics in severely deformed materials.

Recent studies (2023–2025) highlight advancements in nanocrystalline alloy design, shock loading responses, and defect-mediated diffusion mechanisms in carbides. His work bridges computational predictions with experimental validation, emphasizing materials for high-performance applications.

While no formal advisees are listed, his contributions span 20+ peer-reviewed articles since 2016, with ongoing investigations into nanomaterials and defect physics. He collaborates closely with Prof. Yuri Mishin and other computational materials scientists.
