Marco Marazzi is an Associate Professor at the Physical Chemistry Unit of the University of Alcalá, Spain. He obtained his bachelor's degree in chemistry with a major in Materials Chemistry at the Sapienza University in Rome, Italy, his Masters in Polymer Science in Berlin, Germany and his PhD in Chemistry at the University of Alcalá, Spain in 2013, working on the theoretical development and computational application of photochemical and photophysical tools. After postdoctoral stages at the Karlsruhe Institute of Technology (KIT), Germany, as a Humboldt fellow, the French national research council (CNRS), and the University of La Rioja, Spain, strengthening his skills in excited state molecular dynamics and in different photoinduced processes, he was appointed Assistant Professor at the University of Alcalá in 2019. Since then, his interests have included the design of solar energy storage systems, as well as hydrogen release and photoinduced hydrogen production. He was visiting researcher at the University of Uppsala, Sweden, Bowling Green State University, Ohio, USA, Northwestern University, Illinois, USA, and Université Gustave Eiffel, France. He is the author of more than seventy journal publications, four book chapters, and was co-Editor of Theoretical and Computational Photochemistry (Elsevier, 2023) with Cristina García Iriepa
