Biographical Details
Jimmy is a palaeobiologist and 2026 ARC DECRA fellow primarily interested in patterns of morphological evolution across the history of life. He uses morphometric and phylogenetic analysis and to explore morphological diversity in fossil animals at different scales; from studies of growth and development in individual species, to macroevolutionary questions about the rise and fall of morphological disparity on geological timescales. Jimmy mainly uses trilobites as a model group in his research, but has also worked on other groups ranging from the enigmatic Ediacara biota (the first macroscopic life on Earth) to Cretaceous reptiles.
