- Energy storage is a major requirement today than at any time in our history. New batteries, super capacitors, and fuel cells have been identified as key devices for small, medium, and large scale energy storage systems. Thus, my main research interest is studies of advanced materials, in particular those intended for energy storage and energy conversion devices.
- In addition, I do my research on seeking value addition potentials for local minerals available in Sri Lanka. The objective of this research is to utilization of our raw materials in proper way and add value to them rather than selling them as raw form at very low prices
- In both these areas of research, I would like to investigate how fundamental physico-chemical properties of these materials relate to their structure, architecture and interactions
