Esther Rodriguez-Villegas leads a multi-disciplinary team of thirteen Post Doctoral researchers and PhD students. The expertise in the group includes high performance analogue circuit design, biomedical signal processing, electronic circuit packaging, and high performance PCB design.

Her most recent research interests are focused on wearable sensors for breathing and cardiac monitoring and low-power electronics for the online processing of electroencephalogram (EEG) signals. Esther Rodgriguez-Villegas' EEG research is now receiving funding from the European Research Council under the European Community's 7th Framework Programme (FP7/2007-2013) / ERC grant agreement no. 239749. She is part of the Commodity-12 consortium for continious monitoring of type 1 and 2 diabetes and has been awarded the CrackIT Challenge in 2012 which is run by the National Centre for Replacement, Reduction, and Refinement of Animals in Reseearch and is sponsored by Eli Lilly.
