Dr Sandro Mignuzzi is a research associate in the Complex Nanophotonics Group.

His current interests focus on light-matter interactions at the nanoscale, nanoantennas for quantum optics, 2D materials and cathodoluminescence spectroscopy for deep sub-wavelength mapping of the local density of optical states.

Prior to his current position at Imperial College, he was a postdoctoral research associate at King's College London, and a visiting researcher at the National Physical Laboratory (UK) and University of Cambridge.

He holds a Ph.D. in Physics from King’s College London; his dissertation was on nanoscale optical spectroscopy of two-dimensional materials, with emphasis on Raman scattering in disordered crystals and tip-enhanced Raman spectroscopy.
