My research interests are the study of the gas and its role in active galactic nuclei. I look at the interaction between the gas and the radio plasma and exploring the life-cycle of radio sources using low frequency observations (LOFAR) and the combination LOFAR-Apertif. I am interested on the role of gas (and in particular neutral hydrogen (HI 21 cm) and cold molecular gas) in the evolution of early-type galaxies.
