We welcome Dr. Eduardo Martinez to VioBio, who will join projects involving image processing. Eduardo is an Telecommunication Engineer from the Universidad Politecnica in Madrid. He received his PhD by Universidad Carlos III, in Signal Processing, where he was a lecturer in Signal Theory and Communucation from 2006 to 2014.
His interests are compact representation of signals for applications to image, video and biomedical image processing.
CSIC has launched a press release featuring the recent collaborative study between VioBio Lab and Wellman Center of Photomedicine (MGH) just published in the Journal of the Royal Society Interface

Corneal biomechanical properties from OCT Vibrography published in Journal of the Royal Society Interface
The study demonstrates the use of phase-sensitive OCT in combination with acoustic stimulation to obtain mechanical properties of the cornea. A finite-element model shows that the measured resonance frequency of the vibrating cornea is proportional to corneal elasticity.
The method was demonstrated on corneal flaps and intact corneas. The resonance frequency shifted after a cross-linking corneal stiffening procedure. The study is a collaborative work between the Visual Optics and Biophotonics Lab (Institute of Optics, CSIC) led by Prof. Susana Marcos, and Prof. Andy Yun’s lab at Wellman Center of Photomedicine, Massachusetts General Hospital (Harvard /HSTI-MIT)
