Personal profile

Research interests

My research interests are in using periodic gold nanostructures to enhance optical responses of molecules. Metallic nanostructures can lead to strong localized electric fields at the dielectric-metal interface. Additionally, I study chiral materials, which are objects which cannot be superimposed with their mirror images. Chiral objects interact differently with left- and right-circularly polarized ligth. I try to exploit this phenomenon to study the far-field behaviour of chiral, achiral and racemic (i.e. a mix of equal amount of a chiral object and its mirror image) nanogratings. Currently, I am working on exploiting this far-field behaviour for enhanced molecular chiral sensing.

Fingerprint Fingerprint is based on mining the text of the person's scientific documents to create an index of weighted terms, which defines the key subjects of each individual researcher.
