Marcelino Maneiro graduated with an M.S. degree in Chemistry from the University of Santiago de Compostela (USC) in 1993 and received his Ph.D. degree in 1998 under the supervision of Professors Manuel R. Bermejo and Antonio Sousa in Santiago de Compostela, working in the field of coordination chemistry, and, in particular, focusing on the study of manganese complexes as mimetic models for artificial photosynthesis. During his Ph.D. degree period, he also performed different stages in 1996-1997 at the University of Manchester, Institute of Science and Technology (UMIST), UK. From 1998 to 2000, Maneiro was a Postdoctoral Fellow at Princeton University, NJ, USA; in 2004 he was Visiting Researcher at the Royal College of Surgeons in Ireland, Dublin, Ireland. Since 2000, Marcelino Maneiro has occupied different research and academic positions at USC and he became Professor of Inorganic Chemistry at USC in 2007. Maneiro is an author or co-author of more than 70 scientific publications. His research topics focus on biomimetic catalysts, and synthetic inorganic complexes that can simulate the mode of action of a natural enzyme by catalyzing a reaction in ambient conditions. The bioinorganic chemistry of manganese complexes, the study of their peroxidase and catalase activities, and their capacity to catalyse water photolysis are some of his research areas of interest.
