I am a PhD student under the supervision of Miguel Ángel Pérez-Torres and Antxón Alberdi. My work in the thesis involves AGNs and SNRs in the context of the highest angular resolution in radio interferometry, more specifically in Ultra/Luimnous Infrared Galaxies (U/LIRGs). The instruments I am currently using are eMERLIN (UK) and the EVN.
