Professor Alvarez was born in Panama (Republica de Panama) in 1950, where he developed his interest for Chemistry. He moved to Barcelona in 1968 to study Chemistry at the Universitat de Barcelona (UB), where he pursued graduate studies with a grant of the Agustin Pedro y Pons Foundation. He obtained a Ph. D. with a thesis on vibrational spectroscopy under the advice of Prof. Jaume Casabo and in collaboration with V. Tabacik in Montpellier (France). For some time he carried out research on the synthesis and characterization of molecular metals and worked later for one year in theoretical inorganic chemistry in the group of Roald Hoffmann at Cornell University, granted by the Fulbright-MEC postdoctoral program. He was appointed as Profesor Titular (Associate Professor) in the Universitat de Barcelona in 1984 and was promoted to Catedratico (Full Professor) of Inorganic Chemistry in 1987.
His main research interests have been in bonding and stereochemistry of transition metal compounds, combining computational chemistry and structural database analysis. In particular he has dealt with the structure and bonding of several families of coordination and organometallic molecules, the structure and electrical properties of solid state compounds, the magnetic coupling of two or more paramagnetic atoms in complex molecular structures. He has produced over two hundred research papers. The most recent line of activity of his research group consists on the definition and application of the continuous shape measures and the continuous symmetry measures to the systematic description of molecular, supramolecular and crystal structures, developing new stereochemical tools such as the shape maps, the minimal distortion paths, the path deviation functions and the generalized interconversion coordinates.
He was Director of the Department of Inorganic Chemistry of the UB between 1992 amd 1995 and is advisor to the Board of Governors of the UB since 2004. He has been a member of the Editorial Board and of the International Advisory Board of Dalton Transactions, and participated in a IUPAC working party for the study of terminology of theoretical chemistry in 1993. His most recent awards include the Distincio de la Generalitat de Catalunya per a la Promocio de la Recerca Universitaria, Premio de Investigacion en Quimica Inorganica de la Real Sociedad Espanola de Quimica and the Premio Solvay de Investigacion en Ciencias Quimicas. He is Fellow of the Royal Society of Chemistry since 2005 and a corresponding member of the Spanish Royal Academy of Sciences since 2006.
He has been active in organizing scientific meetings, such as the euromediterranean conference of inorganic chemistry FIGIPS-6 in 2001 and several international advanced courses on Synchrotron Radiation and X Ray Absorption, Dessign and Assembly of Molecules and Networks, Photochemistry and Luminiscence of Coordination Compounds or Structural Databases in Chemistry. Starting in 2003, he has organized the international meetings NoSIC (Not Strictly Inorganic Chemistry), in which participants discuss on topics on the borders of Chemistry and other areas of knowledge, such as art, history, language, music or gastronomy. He publishes a section in the Revista de la Societat Catalana de Quimica entitled El Bagul dels Llibres (the ark of books), that reviews the most salient books on topics close to the edges of chemistry and humanistic knowledge. He has also recently published a book entitled Els atoms en l'espai (Atoms in Space), that provides a Catalan translation of the founding papers of stereochemistry by Van 't Hoff and Le Bel, complemented with an assay on the precedents and consequences of such publications.
