The connecting thread of my research is to uncover patterns and processes of genome evolution responsible for plant diversification, through an integrated approach including evolutionary-developmental biology, phylogenetics and cytogenetics.
I am particularly interested in studying the origin and diversification of plant reproductive morphologies across angiosperms from the evo-devo and genomic (e.g. polyploidisation, transposon activity) perspectives. My research concentrates on the changes in floral symmetry and inflorescence complexity in Papaveraceae and the Asteraceae representatives displaying secondary heads (=syncephalia).
My other main research line focuses on the evolutionary significance of the extraordinary diversity of plant genomes (i.e. size, organisation, composition and dynamics), covering a wide array of plant groups including angiosperms, gymnosperms and pteridophytes.
