Chiara Marabelli is a postdoctoral researcher focusing on the crossroad between the biochemistry and biophysics of proteins involved in the Excitation–Contraction Coupling in cardiac physiology and disease. After obtaining her Bachelor Degree in Biotechnology in 2013, and her Master's Degree in Molecular Biology and Genetics in 2015, she started her Doctorate Degree at the Biocrystallography group led by Prof. Andrea Mattevi. Her project led her to solve the Cryo-EM structure(s) of a chromatin remodeller in complex with its nucleosome structure in collaboration with Prof. Sriram Subramaniam. The successful experimental strategy undertaken for an otherwise non-stabile complex was the result of an inter-disciplinary work between chemists and biologists. She broadened her inter-disciplinary skills in the frame of an industrial partnership for the engineering of enzymes as selective biocatalysts for the production of vanillin and bioplastic monomers from pulp fraction. In 2019, she moved to the Cryo-EM Facility at the University of Milan, Italy, led by Prof. Martino Bolognesi, where she assisted with or collaborated on more than 15 projects regarding enzymes and nucleo-protein complexes, membrane channels, ex vivo and synthetic amyloids, and nanoparticles for pharmaceutical use. After her time as an EM Specialist at the Human technophile research centre, Milan, Italy, she moved, in 2022, to the Molecular Cardiology laboratory led by Professor Silvia G. Priori in Pavia, Italy.
