Born: 1978

Interests: ultrafast lasers, optics, near-field, plasmonics, spectroscopy, microscopy, innovation, business management, marketing

I am a recent PhD in Physics from the Humboldt University, Berlin Germany. My main research area was linear and nonlinear optics, and in particular near-field optical microscopy and spectroscopy, ultrafast lasers, AFM. I am now Sales and Application Enginner at Femtolasers Produktions GmbH, an ultrafast-laser producing company in Vienna, Austira.
