After a bachelor degree in Chemistry in 2012 and a master degree in Chemical Sciences at University of Bari in 2015 with a thesis on use of biomaterials for waste water purification, Alessandra landed in Naples in 2018 as Research Fellow at Institute of Polymers, Composites and Biomaterials of National Research Council, studying the thermal properties of Poly(l-lactic acid) under the supervision of Dr. Maria Laura Di Lorenzo. Soon after, the same year, she started her PhD in Product and Process Engineering at FoamLab directed by Prof. Ernesto Di Maio at Dipartimento di Ingegneria Chimica, dei Materiali e della Produzione Industriale of University of Naples Federico II, focusing her research activity on the interplay between crystals and bubbles in physical foaming. Exploiting her knowledge of crystallization mechanisms of PLLA, Alessandra studies the influence of crystals and chain aggregates on foaming and she reached the goal of tuning foam morphology and material thermal properties by simply vary processing conditions. She is currently concluding the last year of her PhD and plans to continue working in research to study novel ways to improve biomaterials properties for the health of the Planet.
