My doctoral research activities have revolved around modeling the effect of disorder on transport and breakdown properties of materials. Various important engineering materials such as concrete, composites, rocks, paper, metal foams, etc. are inherently disordered. Moreover, even weak disorder in the system can be of key importance when dealing with small enough length or time scales. We use simple models to understand the connection between the disorder and the emergent system behavior.
My current research is still about disordered materials, but living or active disordered system of epithelial sheets as compared to the dead or inert ones I’ve encountered before.
As a part of the recently established NSF center for Novel High Voltage/Temperature Materials and Structures, we are also studying electrical conductivity of polymer nano-composites.
