Valentina Parigi obtained her PhD at LENS (European Laboratory for Non-Linear Spectroscopy) in Florence under the supervision of Marco Bellini. During her PhD she worked on  generation, manipulation and characterization of non-classical states of light and she realized the first experimental test on quantum commutation rules.

On 2010 she joined as a post-doc the group led by Philippe Granger at the Institut d’Optique. She worked on the project which aims to implement non-linear effects at the single photon level by exploiting the long-range interactions in ensemble of Rydberg atoms.

On 2013 she worked as a post-doc with Julien Laurat at LKB  on an atomic quantum memory for vector beams. On 2014 she worked with Valentina Krachmalnicoff and Yannick De Wilde on near-field characterization of disordered nanostructures.

Since 2015 she is Associate Professor in the Quantum Optics group at LKB, working in the Multimode Quantum Optics team.
