My research activities are focused on the study and design of novel processes based on the use of membrane technologies and their synergic coupling with supercritical fluids and ionic liquids. Currently, several projects on the design and adaption of these green technologies are in progress to be applied to different fields such as the production of biofuels, treatment of polymers and their modifications, food processing, extraction of metal species and the treatment of wastewaters and gases.
