Research Area
My research involves the design, fabrication and characterization of plasmonic nanostructures that can be actively modulated using a class of material that can phase-transform on an ultrafast time scale. Elucidating the complex dynamics of such hybrid structures both at nanometer length scales and on femtosecond (1x10-15 seconds) time scales will lead to the ultrafast control of nanophotonic systems and fabrication of sub-wavelength components such as optical modulators and autocatalytic nanosensors.
