Sebastiao J. Formosinho obtained his Ph.D. from the Royal Institution at the University of London. He later became a Professor of Physical Chemistry, and subsequently the Dean of his Department and of the Faculty of Sciences and Technology at the University of Coimbra. His research interests focus on unidimensional models of chemical reactivity and structure-reactivity relationships. Professor Formosinho has published more than 160 scientific papers and is co-editor / editor of three books and 2 patents. He has also published articles on chemistry teaching and the epistemology of physical sciences. Sebastiao Formosinho is an active member of the Portuguese Academy of Sciences, holds the EUROCHEM title, and is an IUPAC Fellow. He has also been the recipient of a number of professional awards. Mónica Barroso is a postdoctoral researcher at the University of Coimbra, in the group of Photochemistry and Molecular Spectroscopy. Her current research is focused on nanoscale devices for the conversion of solar energy into clean energies. Prior to that, she was based at the EPFL in Switzerland where she started her studies on solar hydrogen generation with nanocrystalline semiconductor photoelectrodes. Other research interests include photochemical reactions in solution, supercritical fluids, proton-coupled electron transfer, and organic-based photovoltaics. She has received 3 research grants from the Portuguese Science Foundation and 2 awards (from Fundação Calouste Gulbenkian and the University of Coimbra).
