Martin recently completed his Ph.D. research with us on the systematics of early members of the clade Archosauriformes and archosauromorph phylogeny. He is now back in Argentina where he is a member of the CONICET and an Associate Curator at the Museo Argentino de Ciencias Naturales “Bernardino Rivadavia” in Buenos Aires. He remains an Honorary Research Fellow at the University of Birmingham. He has published widely on Mesozoic archosaurs, including early archosauromorphs and dinosaurs, as well as on quantitative approaches to palaeobiogeography.
