**About the Editors**

**Maria Beatrice Coltelli**, Associate Professor of Materials Science and Technology of the University of Pisa, Department of Civil and Industrial Engineering, degree in Chemistry and Ph.D. in Chemical Science at the University of Pisa, has 20 years of experience on material science and technology, in particular the characterization and study of the correlations between molecular structure, morphology and properties of polymers, biopolymers, blends and composites, especially those related to their relationship with the environment. She co-founded the SPIN-PET company aimed at facilitating material recycling and considering circularity aspects linked to the production and use of polymers and materials. She is the author and co-author of more than 70 publications in international journals, a book related to the reuse of polymers and three polymers. She followed the scientific activity of European projects on Material Science, Advanced Materials and Nanotechnology. Currently, she is participating in three European BioBased Industry Joint Undertaking (BBI JU) funded projects promoting the use of renewable and biodegradable materials in packaging, personal care, cosmetic and sanitary applications. She is pro-tempore president of European Network of MATerials Research Centers (ENMAT). She has supported, for many years, the didactical activity of degree courses for Chemical Engineers (courses: Materials Science and Engineering and Science and Tchnology of Polymeric Materials) and Materials and Nanotechnology master courses (course: Reactive processing and recycling of polymers).

**Serena Danti**, Senior Researcher, is Professor of Biomaterials for the Master of Science degree in Materials and Nanotechnology (University of Pisa). She received an M.S. in Chemical Engineering from the University of Pisa in 2003, with a major in Materials Science. She obtained a Ph.D. in "Health Technologies: evaluation and management of Innovations in Biomedical field" from the Center for Excellence in Computer-Assisted Surgery (ENDOCAS), Faculty of Medicine and Surgery, University of Pisa, in 2007. In 2006, she was a visiting scholar at Rice University, Houston, TX, USA. Her postdoctoral training was performed at the Center for the Clinical use of Stem Cells, Faculty of Medicine and Surgery, University of Pisa and at the Otorhinolaryngology Unit, Cisanello Hospital, Pisa (Italy). She is affiliate researcher at Massachusetts Institute of Technology (MIT), Cambridge, MA, USA since 2017, and at the BioRobotics Institute, Scuola Superiore Sant'Anna, Pontedera (Pisa) since 2014. She is a member of 3R's center (Italy). Dr. Danti is involved in international research projects and has published about 90 papers indexed in Scopus, including 12 book chapters. She is an author of more than 120 presentations for national and international conferences, including presentations on biomaterials, tissue engineering and regenerative medicine, ear biology, among others. Her research interests are in smart biomaterials and technologies for tissue regeneration and pathology resolutions, including skin, bone, ear and cancer.
