Dr. Cristina García Iriepa received her BSc in chemistry (Bachelor excellence award) in 2011 and her MSc in Fine Chemistry in 2012 from the University of Alcalá (Spain). She obtained her PhD in chemistry in 2016 studying photoactive devices both, from a computational (at the University of Alcalá) and experimental (at the University of La Rioja, Spain) point of view. After, she performed postdoctoral stages at the Université Marne-la-Vallée (France) studying bioluminescent processes, at the University of La Rioja strengthening her background in molecular photoswitches and at the University of Alcalá. Finally, in 2019, she was appointed Assistant Professor at the University of Alcalá. Currently, she is interested on photochemical processes, particularly focused on the application of molecular devices and photoactive proteins. 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
