Genni Testa was born in Naples in September 14, 1979. She graduated in Physics (Solid State) with 110/110 cum Laude at the University of Naples Federico II, Italy, in october 2005. The final graduation work was focused on the setting up of an experimental set-up for the generation and the analysis of non-classical light, generated by the non linear interaction of a laser source with a non linear poled crystal. The work involved both theoretical and experimental aspects, addressing to algorithms design, development and implementation

She received the Ph.D. degree in Electronic Engineering, at the Second University of Naples, in january 2009. The Ph.D. thesis work was focused on the realization and characterization of liquidi core ARROW-based silicon integrated interferometric optofluidic devices for biomedial sensing application and environmental monitoring. 

From 03/05/07 to 15/12/07 she has been visiting scientist at the Delft Institute of Microelectronics and Nanoelectronics (DIMES) of the Technological University of Delft (Netherlands), carrying out a research activity focused on realization of silicon integrated optical devices. In particular, during this period, she has attended a basic course on the MST/MEMS technology. 

From november 2008 to june 2010 she worked at the Isituto per il Rilevamento Elettromagnetico dell’Ambiente, National Research Council (IREA-CNR), with a post-doctoral position. 

From June 2010 she works at IREA-CNR as a temporary research-scientist. Her research activities deals with integrated silicon based and polymer-based optofluidic devices for biosensing application and environmental monitoring and distributed fiber sensor based on Brilluoin scattering for temperature and strain measurements.
