PhD in Food Science (Brazil) with diploma recognition in Chemical and Biological Engineering (University of Minho), Msc in Food Science and BSc in Pharmacy. Research expertise focuses on extraction, purification and characterization of bioactive compounds and polysaccharides from plants. Researcher at Alchemy Project with the activities related to extraction of polysaccharides and oligomers using chemical and enzymatic methods; purification methods such as ion exchange resins, ultrafiltration and selective crystallization. Characterization of biopolymers and oligomers from natural sources using chemical (chromatographic sugar profile, minerals, proteins) and rheological methods (caking strength, cohesion index, compressibility, stiffness, density, powder stability). Development of new products, namely hydrogels, based in cellulose/derivatives and other biopolymers for sustained release of bioactive compounds.
