Dr. Sergio E. García-Garrido obtained a degree in chemistry from the University of Oviedo in 2000 and completed his Ph.D. in 2005 under the supervision of Prof. José Gimeno and Dr. Victorio Cadierno, working on the chemistry of organometallic complexes of ruthenium(II) and ruthenium(IV), as well as their application in different catalytic processes of interest. After a postdoctoral stay (2005–2007) at the School of Chemistry of Southampton University (Southampton, UK), working in the field of supramolecular chemistry and its application in the recognition of anions, he rejoined the Department of Organic and Inorganic Chemistry of Oviedo University, first as a contracted researcher (2008) and later as a Ramón y Cajal researcher (2009–2013), assistant professor (2014–2018) and, finally, as an associate professor in inorganic chemistry, a position that he currently performs. His current lines of work focus on the chemistry of organometallic complexes and the development of new supramolecular structures, as well as their applications in homogeneous and heterogeneous catalysis.
