BIOGRAPHY:Giorgio Adamo is an Associate Professor at the Optoelectronic Research Centre (ORC), University of Southampton, UK. He is an expert in nanophotonics and super-resolution microscopy, with research focusing on light–matter interactions in advanced nano-optoelectronic systems and their visualization at deep subwavelength scales. Giorgio obtained his Laurea (integrated BSc–MSc) from the Polytechnic University of Milan and an MSc from KTH Royal Institute of Technology, both in 2005. He received his PhD from the ORC at the University of Southampton in 2011, and was awarded an EPSRC Doctoral Prize. In 2012, he moved to Nanyang Technological University (NTU), Singapore, where he contributed to the establishment of the Centre for Disruptive Photonic Technologies (CDPT) and was appointed Research Manager. In 2019, he was awarded the Mistletoe Research Fellowship. He joined the University of Southampton as one of 2026 UK Global Talent Fund Awardee.

ABSTRACT:The unique combination of high refractive index, structural phase-change, excitonic luminescence and charge transport properties of halide perovskite films enables the realization of monolithic dielectric nanostructures with complex optical functionalities. In this talk, I will discuss few examples which show how merging perovskites with the metasurfaces design paradigm creates ideal platforms for the realization of tunable microlasers [1,2], for the optical and electrical generation and control of exciton-polaritons [3], as well as the creation of polariton condensates, where the metasurface design underpins the formation and geometry-driven control of topological excitations within the exciton-polariton fluid [4].
