Professoressa Associata di Chimica Fisica presso l’Università di Pavia e Direttrice del gruppo di ricerca PVsquared2 presso il Dipartimento di Chimica dell'Università di Pavia

Professional career

Giulia received an MS in Physical Engineering in 2008 and obtained her PhD in Physics cum laude in 2012 at the Politecnico of Milan. Her experimental thesis focused on the realisation of a new femtosecond-microscope for mapping the ultrafast phenomena at organic interfaces. During her PhD, she worked for one year at the Physics Department of Oxford University where she pioneered new concepts within polymer/oxide solar cell technology. From 2012-2015, she was a post-doctoral researcher at the Italian Institute of Technology in Milan. In 2015, she joined the Ecole Polytechnique Fédérale de Lausanne (EPFL) with a Co-Funded Marie Skłodowska-Curie Fellowship. From 2016 to 2019, she has been awarded by the Swiss Ambizione Energy Grant providing a platform to lead her independent research group at EPFL. Since July 2019, Giulia is Associate Professor at Physical Chemistry Unit at University of Pavia, leading the PVsquared2 team, and PI of the ERCStG Project “HYNANO”aiming at the development of advanced hybrid perovskites materials and innovative functional interfaces for efficient, cheap and stable photovoltaics. 

Scientific results

Her research interest is focused on exploring the fundamental photophysical properties and dynamical processes behind advanced materials and devices, with a special attention to nanostructured semiconductors for the development of new generation solar cells.  Within this field, Giulia contributed to reveal the fundamental light-induced dynamical processes underlying the charge generation mechanisms happening on ultrafast time scale whose understanding is paramount for a smart device optimization. In particular, she made seminal contributions in ultrafast science applied to investigate the interface physics in polymer blends, and hybrid polymer/oxide systems. With the ERC “HY-NANO” project, her recent research is focused on the design and the study of HYbrid NANOstructured multi-functional interfaces for the development of advanced photovoltaic devices based on low dimensional hybrid perovskite semiconductors. More in details, her multidisciplinary team aims at expanding the family of hybrid perovskite materials and interfaces as lego-bricks for a new generation of efficient, stable, environmentally friendly solar technology.
