  • among the first researchers in Romania to work on plasmonics of ordered nanostructured metal surfaces.
  • developer of an original convective self-assembly method, named "Stop&Go Convective Self-Assembly" (ACS Nano 2011, 5, 9, 7137–7143).
  • demonstrated for the first time SPR spectroscopy, SERS and MEF on the same plasmonic substrate (2008, PhD thesis).
