Qualifications: M.Sc. in Communication Systems Engineering, University of Zaragoza
Ph. D. in “Information and Communications Technologies in mobile networks”, University of Zaragoza


After obtaining my M.Sc. in Communication Systems Engineering by the University of Zaragoza in 2005 I’ve been working as a researcher for the Zaragoza University, first as a granted student and later I become an assistant researcher where I worked mainly in optical access networks and POF fibres. I received my Ph. D. in “Information and Communications Technologies in mobile networks” from Zaragoza University in 2011. In April 2012 I accepted a position as a research fellow in the University of Glamorgan (Wales, UK) where I’ve started to work in other fields of electro-optical science such as optical metrology and where I’m currently stay.

The orientation of my Ph. D. along with all the work of the last years has given me a very strong background in experimental and lab work. With a great knowledge of lab devices and equipment and a positive attitude to propose and evaluate experimental schemes

Main Research Areas:

Optical Communications, Passive Optic Networks (PON), Access optical Networks, Semiconductor Amplifiers (SOA), Frequency Scanning Interference (FSI) metrology, Optical Metrology, Plastic Optic Fibre (POF).
