Professor Marini graduated in 2000 from the University of Rome La Sapienza, where he also obtained his PhD in 2004. During his doctoral studies, he was awarded a three-month Marie Curie fellowship at the National Institute of Chemistry (Ljubljana, Slovenia) under the supervision of Professor Marjana Novic. After four years as a research fellow (2004–2008), in 2008 he was appointed as a Researcher at the University of Rome La Sapienza, where he served as Associate Professor from 2018 to 2021, and since 2021 has
In 2006, he received the Young Researcher Award from the Analytical Chemistry Division of the Italian Chemical Society, and in 2012, he won the Chemometrics and Intelligent Laboratory Systems Award "for his significant contribution to the development of chemometrics." He has been a visiting researcher at various universities (Copenhagen, Stellenbosch, Silesia, Lille) and research institutes (National Institute of Chemistry, Slovenia; Nofima, Norway; Irstea, France).
His research activity focuses on all aspects of chemometrics, ranging from the application of existing methods to real-world problems (in multiple fields) to the design and development of new algorithms. He is the author of over 300 publications, including articles in international journals and book chapters, and in 2013, he edited the book Chemometrics in Food Chemistry (Elsevier).
He is the Editor-in-Chief of Chemometrics and Intelligent Laboratory Systems and a member of the editorial boards of Analytica Chimica Acta, J. of Chemometrics, J. of NIR Spectroscopy, J.of Spectral Imaging, and Food Control; he is also Associate Editor for Chemometrics in Wiley's Encyclopedia of Analytical Chemistry. He has served as the coordinator of the Chemometrics group of the Analytical Chemistry Division of the Italian Chemical Society and is currently the Vice President of the Italian Society of NIR Spectroscopy and the coordinator of the Chemometrics Task Group of DAC-EuCheMS.
