Research Interests

I am currently working on nanofabrication using glancing angle deposition (GLAD) or dynamic shadowing growth (DSG), chemical and biological sensor development based on surface enhanced Raman spectroscopy (SERS) or plasmonics, plasmonic structure amd matematerial fabrication, characterization, simulation, and understanding, novel nanocatalyst and photocatalyst development and applications, nanomotors and novel stroke treatment strategy. More information can be found at my research website.
