Rohit is interested in developing theories and using computer simulations to understand microstructure formation and evolution in materials. His work is focused on understanding the early stages of oxidation and corrosion of alloys as part of the ONR MURI "Understanding Corrosion in 4D".
Rohit's work involves understanding the phenomenon of passivity of metals due to the formation of thin oxide film on their surfaces. Of particular interest is understanding how the passive state can break down locally, leading to harmful pitting corrosion of the underlying metal. He studies these phenomena by developing and refining defect models for the growth of passive oxide films, and using linear stability analyses to study pitting breakdown.
