Josua’s Brief Professional and Personal Bio:
I studied Physics at Universidad de Granada (Spain), and obtained a Master Degree in Astrophysics at Universidad de La Laguna (Spain) in 1999. I also got the International Student Diploma at the Imperial College of Science, Technology and Medicine (UK). Then I enrolled in the PhD program of Applied Chemistry at the Universidad de Murcia (Spain), obtaining the Advanced Studies Degree (Diploma de Estudios Avanzados) in 2001. In 2003 I was honored with the Young Investigator Award, granted by the Spanish Optical Society and the Royal Spanish Physics Society. I completed my PhD thesis in 2004, supervised by Pablo Artal, whom I continue collaborating with. I moved from Astrophysics to Physiological Optics in my thesis, applying some astronomical optics techniques to correct telescopes’ images from the atmospheric turbulence to the human eye optical aberrations. That’s adaptive optics (AO) about, one of my main research lines since then. This technology is capable of measuring in real time ocular aberrations, for their subsequent correction and/or manipulation. The possibilities of studying the eye while free from its inherent aberrations are enormous from several perspectives.
Right after defending my thesis I moved to Vienna (Austria), where I worked for slightly more than two years applying AO in ultra-high resolution optical coherence tomography (UHR OCT) for the human retina. That was in the nice group of W. Drexler, at the Zentrum für Biomedizinische Technik und Physik (Institute of Medical Physics and Biomedical Engineering, University of Vienna). I suggested the correction of chromatic aberration together with AO for OCT, introducing the term pancorrection. Using pancorrection we achieved unprecedented transverse and axial resolution in the living eye, resolving for the first time subcellular features of the photoreceptors. Because of that, I was honored with the Pascal Rol Award 2006, granted by SPIE, the International Society for Optical Engineering (USA).
In 2006, I came back to Universidad de Murcia as an assistant professor, and I obtained my national habilitation as associate professor. Since 2007, I am associate professor (tenured) in Optics at the department of Physics of the Universidad de Murcia. I spend most of my time investigating the eye and its optics from different perspectives. I find it fascinating. If you are interested in knowing more details about my research activities, you will find further information below in the selected papers’ list.
I have also experience setting with other colleagues a spin out company in Murcia (Voptica SL). This company has developed a commercial instrument AO-based for the advanced retrieval of the refraction, and simulation of vision. In addition to my academic position, I also collaborate regularly with Voptica, trying to develop new solutions and instruments. This is an endeavor I really enjoy for it allows me to make useful to patients my research ideas.
Among other things, I am also teaching Physiological Optics, basic and advance courses, at the School of Optometry in Murcia. I have initiated and directed a Master in Advanced Optical Techniques for Applied Ophthalmology in last years.
Currently, I am also working on intraocular lenses (IOLs) design. I am especially interested and motivated to find a solution that really restores accommodation in the presbyopic eye. It could be based on the triplet lens design. If I success, you might wear one of these IOLs in the future!

When not working (yet often thinking about work), I really love spending the time with my wife and our three fantastic kids. I very much enjoy staying with good friends (not very original, it’s true), jogging, casterboarding (you have to see me), listening to music, playing piano (badly), guitar (even worse), singing (…), and reading -mostly classical, Greek and Roman- literature. And of course, always with the Sea around.
