I'm carrying out my PhD research activity in the Nanoscopy&NIC Lab in IIT, supervised by Professor A.Diaspro. My work concerns the improvement and the optimization of the illumination stage in a multimodal microscopy setup, known as Multi Messenger Microscope. This project is going to integrate several microscopy imaging techniques in the same optical setup in order to realize a versatile instrument with tunable performances. Currently we are working on CIDS and Mueller Matrix Microscopy channel so, I'm studying the best strategies and methods to deals with polarization control of the laser beam. My further research interest are related to laser engineering and nonlinear optics.
