Main research topics

My main focus in the team is to develop and synthesize new fluorescent ligands able to prevent the Cu-Aβ-associated toxicity and ultimately rebalance Cu between intra- and extracellular compartments, and to gain fundamental knowledge about key molecular processes in AD context for therapeutic purposes.
