Research @ IDEAs Lab

We are interested in developing a fundamental understanding of interfaces in materials and their role on thermodynamics and kinetics of materials processing and performance. The materials systems of interest include disordered alloys (metallic glasses, high-entropy alloys), high-temperature materials (Ni-based alloys and coatings, refractory metal silicides, ultra-high temperature ceramics) and nanomaterials (synthesis via self-assembly, ice-templating and far-from equilibrium processing). We employ a diverse vaiety of mathematical, computational, characterization, synthesis and processing tools in our research. The holy grail for our efforts lies in the development of a holistic theory of interface evolution and interface driven materials engineering.

As a part of our research, we are currently developing codes for Materials Informatics and Cellular Automata models of materials. Yet another thrust area is development of in-situ methods during materials processing and performance (e.g., high temperature oxidation).

Disordered Solids

Our efforts in this area focus largely on phase selection (glass formation, nano-crystallization, structure prediction via informatics and modeling of phase stability). The phase stability and microstructural assemblage has a strong bearing on the mechanical properties of these materials.

High-Temperature Alloys

Current effort is largely focused on the development of next generation Ni-based superalloy systems for AUSc and aerospace applications.

We also investigate design of Ultra-high temperature ceramic coatings and Mo-Si-B alloys, their oxidative stability and processing.

Nanomaterials

This is a relatively recent thrust area within our research group, where we focus on understanding and controlling novel (often far-from equilibrium) processing methods ranging from self-assembly to ice-templating, with a focus on the role of interfaces on the evolution of nanostructures.

Materials Modeling

Our efforts in computational materials modeling focus on primarily three avenues - development of data-driven models for alloy design, mesoscale models of microstructure evolution and thermodynamic modeling. Additionally, we also focus on mathematical modeling of interfaces.
