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 multimodal
chromatographic systems operated under axial and/or radial modes. The
thermodynamics of mAbs interaction with the different chromatography
ligands and polymers are also of great interest in my research. I’m
also focused in the optimization of the production of mAbs using
mammalian cell technology.
