Research Interests

Currently I’m integrated in the Biotechnology and Bioprocess Development cluster of CBT, from iMed.ULisboa.
My knowledge on physical, chemical and biological processes is used in emerging biotechnology approaches for the bioproduction of drugs, pointing to:
i. Design and develop value-added bioactive compounds (e.g. peptides, glycosides); ii. Design and modulation of improved bioconversion processes; iii. Modulation enzyme activity and stability by High Pressure and High Temperature technology.
