Research Interests

My research expertise and interests span the device and material design to enhance the performance of energy storage (e.g., (photo)batteries, supercapacitors, and fuel cells), energy harvesting/conversion (e.g., solar cells and water splitting), and electronic (e.g., transistors) devices by improving the inter-grain particle and inter-layer interface and interphase properties of their electrode and/or active materials using advanced interface engineering strategies.
