Research Focus/Background:

The primary focus of our research is in demonstrating innovative processing strategies for nanostructured materials and functional hybrids engineered for challenging applications in clean and renewable energy.

Based on the comprehensive understanding of synthetic chemistry and structure-property relationship with careful characterization of nanostructures and their functionality, we study the fundamentals and application of nanostructure interfacial engineering that entails molecular design and rational synthesis of nanostructured materials and hybrids for membranes, catalysts, and adsorbents with tailored properties.

Nanostructured materials and functional hybrids developed in this research can be incorporated in engineering devices for the application of carbon capture and sequestration, chemical sensors, fuel cells, and production/purification/storage of renewable energy such as hydrogen.
