My research interests combine areas of analytical chemistry, physical chemistry, materials science, and biophysical chemistry. In general, I am interested in studying the optical properties of semiconductor and metal nanoparticles with emphasis on their applications as luminescent probes (in the case of semiconductor nanoparticles) or surface-enhanced Raman scattering substrates (in the case of metal nanoparticles). I am also interested in the assembly of nanoparicles through chemical linkage, such as DNA mediated assembly, and through self-assembly.
