Francisco A. Macías was born in La Línea de la Concepción, Cádiz, Spain (1956). He is Professor of Organic Chemistry at the University of Cadiz, (Spain) since 2000 and Head of the Institute of Biomolecules (INBIO) since 2014. He has been honoured with the 1999 Rhône-Poulenc Rorer Award, Amsterdam, The Netherland, from the Phytochemical Society of Europe (PSE), 2011 Molish Award, Guangzhou, China, from the International Allelopathy Society (IAS) and Gold medal, in Recognition of a Research of excellence, dedication and humanity, The European 2001 Forum, February 2015. Their general philosophy is to learn from Nature. His research interest is related with different aspects of Allelopathy including higher plants and microorganisms, involves studies on natural and modified ecosystems, and developing of new methodologies for allelopathic studies including mode of action. He heads the “Cadiz Allelopathy Group” which is pioneer in Europe in Allelopathic Studies from the Organic Chemistry viewpoint with a multidisciplinary structure. During this period, his group has isolated, identified, characterized, synthesized, and tested the bioactivity of more than 2600 potential allelochemicals and derivatives belonging to a wide range of chemical families as aglycons and/or glycosides (simple phenolics; coumarins; flavonoids; lignans; terpenoids: mono-, sesqui-, di-, spirodi-, mero- and triterpenoids; steroids; benzoxazinoids; within others) that allows the corresponding SAR studies. He is author of 11 international patents. His publications exceed 285, with book chapters; he has co-edited 2 books on Recent Advances in Allelopathy and has supervised 30 Doctoral Theses and delivered more than 350 lectures around the world.
