| Areas of expertise |
My interests include the diversification of life through time, quality of the fossil record, shapes of phylogenies, age-clade congruence, mass extinctions, Triassic ecosystem evolution, basal diapsid phylogeny, basal archosaurs and the origin of the dinosaurs.
Current research projects focus on the end-Permian mass extinction, the greatest mass extinction of all time, and especially its effects on terrestrial organisms. This involves fieldwork in Russia. I am also working on large-scale aspects of dating the tree of life, and the use of phylogenetic means to assess the quality of the rock and fossil records.
