My research concerns protein self-assembly related to neurodegenerative diseases with the focus on characterization of protein structure and molecular mechanisms of self-assembly. The studies in our lab include a broad range of different techniques within biophysicsprotein biochemistry and biomedicine. My current research focuses on the aggregation mechanisms of amyloid-β peptide (Aβ) fibril formation, associated to Alzheimer’s disease and inhibition mechanisms by the BRICHOS domain, a chaperone-like protein that is potential candidate to be implemented in Alzheimer’s disease treatment. Furthermore, another research line is the development of new expression and purification protocols for aggregation-prone proteins using a spider silk-derived solubility tag, where one possible application is the generation of new biomaterials.
