2-year Postdoctoral Advanced Fellowship in Biophotonics @VioBio_Lab



The Visual Optics and Biophotonics Lab seeks candidates for a 2-year COFUND Postdoctoral Application in Biophotonics to develop projects of excellence/innovation in the area of ocular imaging, ocular biomechanics and/or vision correction

The Multiply COFUND Program

The Multiply COFUND Fellowship is partially funded by the European Commission (H2020 Marie Sklodowska Curie Program) and VIOBIO Laboratory Funds.

• Salary: 53,000-55,000 €/year (including Social Security obligations).

The successful applicant will work on development and applications of imaging techniques in the anterior segment of the eye, ocular biomechanics or adaptive optics. Applications range from understanding the basic ocular mechanisms to the evaluation and new designs of alternatives for vision correction.

Full description of Fellowship Program:

Fellowship Starting date: November 2017

Eligible Candidates

Eligible candidates are international or Spanish citizens that have not resided in Spain for more than one year in the previous three years.

Must hold a PhD degree and an excellent background.

Experience in Biomedical Imaging (Ocular imaging preferred) with strong motivation for multidisciplinary research in the field of ophthalmic and ocular biology applications

 Must be fluent in English.

The Visual Optics and Biophotonics Lab

The Visual Optics and Biophotonics Lab, led by Prof. Susana Marcos, provides a young and dynamic research environment. The laboratory is funded primarily by European grants (ERC Advanced Grant), national programs and holds excellent collaborative programs with top international laboratories, clinical institutes and industry. The Lab is part of t EU MyFun Marie Curie ITN Research of Excellence, MIT M+Vision Consortium, among others. The Institute of Optics (CSIC) is the oldest research institute in Optics in Spain, and holds an excellent reputation of research in optics, particularly in Visual Optics. CSIC ( is the National Center for Research in Spain, and the most important multidisciplinary research facility in the country, and among the highest ranked in Europe.

We have compiled a slide show presenting the peer review publications by VioBio Lab in 2016.  Topics include corneal biomechanics, crystalline lens, wavefront sensing and visual simulations of multifocal corrections for presbyopia, and journals include IOVS, Biomedical Optics Express, Optica, PLOS One, Journal of Cataract and Refractive Surgery, Applied Optics and Journal of Refractive Surgery.

Please, visit this link to learn more on what came out from VioBio in 2016.

SimVis technology featured in Ophthalmology Business

The Ophthalmology Business Review has featured the article “Portable device simulates different IOLs before surgery” which describes SimVis, a portable see-through visual simulator of multifocal corrections. The system is based
in the concept of temporal multiplexing (Dorronsoro et al. Optica 2016) and its current version is binocular and wearable. SimVis is developed by 2Eyes Vision, a spin-off company of VioBio Lab-CSIC

We used model polymer corneas of different materials and thicknesses and porcine corneas ex vivo (at constant intraocular pressure) to validate an inverse optimization approach to retrieve material properties from air puff corneal deformation imaging. Material properties were compared with those obtained from uniaxial extensiometry revealing high similarity.  In polymer artificial corneas material properties were retrieved independent on corneal thickness. The study demonstrates that the combination of air puff corneal deformation imaging with inverse modeling is a reliable non-invasive technique to estimate corneal mechanical properties. The study has just been published in PLOSOne.
