Research Statement

My primary research interest is in materials modeling and microstructure engineering of new materials for applications in extreme environments. Currently, the focus of my research is on the engineering of refractory materials (tungsten alloys) for improving the efficiency of thermal power plants, fusion reactor materials, materials with superior toughness and thermal stability for use in the aerospace and automobile industries. The overarching goal of my research is to design new materials by exploring the hierarchical structure-property relationships operating at multiple scales.

The research topics described above bring into focus some of the fundamental open questions in mechanics and metallurgy such as the phenomena of recovery, recrystallization and grain growth which are different stages of microstructure evolution occurring at the atomic scale but which manifest themselves in macroscopic properties. Classical continuum models are often insufficient to predict these complex phenomena due their inherent multiscale nature. On the other hand, atomistic models have the potential to predict such phenomena, but often cannot extend into experimentally measurable spatial and temporal scales. Models at the mesoscale, which enable a continuum description of the microstructure, are ideal to model microstructure evolution as they are computationally tractable. The central theme of my research is to formulate truly predictive thermodynamically-consistent mesoscopic models, with material parameters obtained from atomistic simulations. This requires establishing a rigorous link between the hierarchy of models.
