Research Activities

The overall goal of my research is to develop scalable, integrated and innovative downstream processes for the purification of monoclonal antibodies (mAbs) based on clarification (cell harvest) by extraction using aqueous two-phase systems, and further purification by chromatography using convective flow adsorbers (monoliths, membranes and fibres). The thermodynamics behind polymers, different chromatography ligands and mAbs interactions are also of great interest in my research. I’m also focused in the optimization of the production of mAbs by mammalian cell technology.
