Projects
My main research focus is the characterisation of non-canonical nucleic acid structures (such as G-quadruplexes) and how proteins interact with them. I am particularly interested in repeated sequences and in the evolution of telomeres (the nucleoprotein structures that protect the ends of eukaryotic chromosomes), a fascinating illustration of the unity and diversity of Life.
