Current research engagements:
• Currently, working towards derivation of a new curvature-driven 3D grain growth equation by taking into consideration both the geometrical properties and the topological changes associated with the grains, which can better describe the dynamics of 3D grain growth in space-filling polycrystalline structures. So far, the proposed grain growth models are either purely topological or geometrical. Whereas, just like what Smith had proposed, 3D grain growth is the result of the interaction between 3D grain geometry and topology.
• Another area currently working on is 'Development of topological methods for characterization of cellular structures and to study their evolution'. Normally, grain face is treated as the most intuitional parameter to describe the grain topology, only using faces as variable of the grain growth kinetic equation is not adequate to describe the role that grain topology plays in the course of grain growth. There are other quantities like triple lines and quadruple points etc. The grain face number in grain growth equations must be replaced by a topological index which can completely describe the grain topology.
