Rohit is interested in developing theories and using computer simulations to understand microstructure formation and evolution in materials. Currently, 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”. His initial work focused on developing a thermodynamic and kinetic model of oxide island growth and coalescence that accounts for the polydispersity of the size distribution and its evolution in time.
Recently, Rohit has begun studying the development of morphological instabilities during oxide growth. The oxide films that form on metals are subject to stress and strong electric that can affect the stability of a planar film. The development of these instabilities can lead to unwanted destruction of the film such as delamination from the surface or pitting and environmentally assisted cracking.
