Research Interests:

I am interested in the theoretical and numerical analysis of microstructurally complex materials and devices, properties, and the processing operations that create them. My research centers on material applications for energy storage and conversion devices, actuators, and sensors. Current applications include next generation rechargeable batteries, fuel cell technologies, phosphor-free LEDs, and ferroelectric materials. I am particularly interested in the interrelations between the crystallographic anisotropy of the single crystal properties of each phase in topologically complex solids and its associated macroscopic response, as well as the reliability in a part or device. Of great relevance to my research are the development of novel numerical methods, algorithms, and software.


Impact Statement & Explanation of Research:

Our research group is interested in the application of theoretical and computational methods to understand the relations between material properties, microstructure, and microstructural evolution. Emphasis is placed on the analytical description of complex processes whenever possible and on the development of numerical algorithms and codes for microstructural simulation whenever . We are also interested in developing the means to optimize materials through fundamental understanding and scientific visualization of the relations between processing, structure, and properties.

The current focus is on the description of multifunctional material properties and its application to technologically relevant problems. Example applications include advanced rechargeable lithium ion batteries, ferroelectric microstructures, thermoelectric generators, solid oxide fuel cells, solid state light emitting diodes, and multiferroic materials. For these applications careful consideration is made to understand the interactions of the material phases at the mesoscopic level.

Whenever required, analytical tools, algorithms, and codes are developed for improving materials performance to better understand the relation between processing, structure, and properties. Such tools are being made public to the scientific community, as they become available.
