Short Biography

I started my career in Physics at the National University in Uruguay, where I obtained my BSc and MSc. There I was a pre-doctoral reseach assistant in the Applied Optics Group from 1996 to 2000. Over that period I participated in several reseach projects in the areas of scalar diffraction theory, optical correlation, polarimetry and interferometric optical fiber sensors.

In 2000 I joined the Photonics Group at Imperial College London as a PhD student to pursue my main research interest, the application of optics to the understanding and improvement of vision and ophthalmology. I spent the following three and a half years developing and testing an interferometer for the study of the tear film dynamics and its effects on vision, under the supervision of Chris Dainty and Carl Paterson. Throughout the doctorate studies I also became involved in ophthalmic wavefront sensing and adaptive optics projects. This work lead to a postdoctoral position in the Photonics Group at Imperial developing a low cost adaptive optics toolkit.

Since I joined David Williams' group, in 2006, I have been working in adaptive optics scanning laser ophthalmoscopy, developing novel imaging modalities to visualize retinal structures at cellular level in vivo.
