Sílvia Barbeiro is currently visiting the Acoustics Research Institute (ARI). Her research interests are in numerical analysis and computational mathematics, including modeling and the development and analysis of numerical methods for partial differential equations and integro-differential equations. The main applications driving her recent research are in the fields of electromagnetic wave propagation and image denoising. The aim of her visit at the Acoustics Research Institute to develop collaborative work with members of the group Mathematics and Signal Processing in Acoustics, namely in the field of image processing, taking advantage of the affinities in certain characteristics of the fields of interest.
