###### Research Interests

\

My group specializes in the fabrication of micro/nanostructures and their use in energy conversion devices and optical devices with sub-wavelength dimensions. By advancing micro/nanofabrication techniques, we are able to design and fabricate micro/nanostructures that interact strongly with their external environment. For example, efficient sorption of airborne water molecules on mesoporous materials can be used for cooling purposes, and enhanced light-matter interactions in metallic structures can be exploited to realize highly sensitive sensors for biological/medical applications or ultra-fast all-optical switches for telecommunications. Current research topics include control of thermal emission using micro/nano structuration, surface-wave devices for bio-detection and all-optical switching, and all-optical force sensors using transparent elastic structures.
