Luis R. Domingo obtained his PhD in Organic Chemistry in 1987. In 2010 he obtained his current position of Full Professor at the Department of Organic Chemistry of University of Valencia. His research interest is the study of organic chemical reactivity using quantum chemical procedures based on the analysis of the electron density. He has published more than 300 articles. He has developed several reactivity indices within the Conceptual Density Functional Theory (CDFT) and he has proposed a new reactivity theory named Molecular Electron Density Theory (MEDT) based on the analysis of the changes of the electron density along an organic chemical reaction, and revealing that established theories based on molecular orbital analyses are entirely outdated.
