     My present research focuses on the application of Physics and Photonics methods, concepts and devices to analyze, assess and solve issues relevant to light pollution , i.e. the unwanted effects associated with the alteration of the darkness of the natural night due to the emissions of artificial light. This subject is an emerging field of knowledge that has aroused in recent years a growing interest among the scientific community. Besides the widely known consequences of the increased skyglow for science, in particular for optical astronomy, the misuse of artificial light at night has been shown to have measurable and negative side-effects on global energy consumption, ecosystem dynamics, human and animal health and on the preservation of key aspects of humankind's cultural intangible heritage.

EFixemosALuz     In previous years my research dealt (and still partially does) with the human visual system, particularly in areas directly related related to the optical quality of the eye: eye aberrometrywavefront sensing, and microoptics. In collaboration with several of my research colleagues and PhD students of the Photonics4Life group of the USC we have developed a comprehensive analysis of the human eye statistics and of the way clinical aberrometers work, what are their limitations, and how can they be improved. You may want to have a look to some of our published results. This research has been carried out in cooperation with a number of scientists and institutions: City University of London, Institute of Optics (Spanish CSIC), Scheppens Eye Research Institute (Harvard Medical School), Warsaw Technical University, Institute for Applied Optics (Warsaw), ICMA (Zaragoza, Spain), Institute of Astronomy of the UNAM (Mexico) and Universitat Jaume I de Castelló, to mention but a few.   

     Science dissemination and outreach is an essential part of present-time scientific work. You may find some info about it in the Publications, Visual Astronomy and Social Astronomy sections of this site.
