Research Statement

I have been working on research of micro/nanoscale energy transport and its engineering applications since my PhD. My expertise lies on tip-based thermal applications using heated cantilevers and fundamental physics of near-field thermal radiation . I have also worked on the energy interactions between nanostructures and consequent thermal, electrical, and optical responses. Through my previous experiences, I have gained experimental and theoretical backgrounds in different disciplines - micro/nanoscale thermal engineering, near-field optics, and micro/nanofluidics. My current research foci can be grouped in three main directions; (1) Tip-based nanoengineering - imaging, spectroscopy, and manufacturing, (2) self-assembly of liposome-templated multifunctional nanostructures and applications, and (3) multiscale renewable energy conversions, including near-field thermophotovoltaics, solar thermal, and pressure-retarded osmosis power generation.
