Doctorate in Chemical Sciences for the Kadi Ayyad University (1986, Marrakech). During 1986-1990 I worked at the Institute of Physical Chemistry of the CSIC (Madrid). During 1990-1992, he was a postdoctoral fellow at the Ministry of Science and Technology of Japan and the "Japanese Society for the Promotion of Science, JSPS "working at the Institute of Molecular Sciences in Okazaki (Japan). During 1992, I worked as an associate researcher at the "Laboratoire de Photophysique Moléculaire ", CNRS-University Paris-sud, Paris (France). In 1993, he joined the UCLM (Chemical Section in Toledo) as guest lecturer, and later As a contract associate professor. Since 2007 he is a university professor (Department of Physical Chemistry). He has been a guest researcher for several Seasons (1995-2000) by the California Institute of Technology, Caltech), collaborating With Professor Ahmed Zewail (Nobel Prize in Chemistry, 1999) in Femtochemistry and Femtobiology. He is a member of the "American Association for The Advancement of Science (AAAS), the IUPAC, the European Photochemistry Association (EPA), "Spanish Photochemistry Group" (GRUFO), and the Royal Spanish Society of Chemistry (RSEQ).

His recent research is in nanoscience (nanofotonica, nanomedicine and nanocatalysis) Focuses on the study of atomic-scale molecular events in pockets and channels Molecules such as proteins, micelles, zeolites, nanomaterials based on silica, and dots Using various techniques of femto-second laser Millisecond, and fluorescence microscopy for individual molecules results in the Time and space. The research group (between 10 and 2 researchers) Of 5 research laboratories with infrastructure of high technological level.
