Background

Silvia’s areas of expertise include numerical modelling of physical processes (wave propagation for acoustics/electromagnetics/optics, psycho-acoustics, electron transport), image/sound/signal processing, artificial intelligence, optical systems, inverse problems and statistical methods. Since 2010, she has worked with the Vision and Eye Research Institute (VERI) on the role of acoustic cues, like level and reverberation as conveyors of information about the environment and to facilitate better navigation of the visually impaired. She has a keen interest in the area of assisted living for the visually impaired using acoustic cues and smart technologies.

She has worked on research projects funded by the EU, UK Central Laboratory of the Research Councils, Radiocommunications Agency, Medical Research Council and British industry.
