Prof. Dr. Mário J. F. Calvete received his Industrial Chemistry diploma from the University of Coimbra in 2000 and his PhD in Natural Sciences–Organic Chemistry in 2004, from Eberhard Karls University of Tübingen, Germany. After a two-year stay at Tübingen as a postdoctoral fellow in Industry/University, he returned to Portugal for a postdoctoral stay at the University of Aveiro. In 2010 he was appointed as an Auxiliary Researcher at the University of Coimbra and since 2019, he has been Assistant Professor at this university. His current research interests are tetrapyrrolic macrocycle design and other heterocyclic ligands and their uses in theranostics and homogeneous/heterogeneous (photo)catalysis, particularly in environmental remediation technologies.
