Research summary

My research is focused on using the fossil record to understand the early evolution of skeletons in animals. The earliest unequivocal animal fossils appear in the rock record almost ‘overnight’, largely in the form of microscopic disarticulated skeletal elements, an event known as the Cambrian Explosion. Locked within these shells, teeth and bones is a record of the expression of the molecular and developmental machinery that drove this event. By using high magnification electron microscopes and 3d x-ray imaging I can peer into the tiny differences in their microscopic internal structures and measure the variability of the shape of individual teeth, spines and shells. Using these data, I am able to disentangle the ecological, environmental and developmental drivers of the origination and diversification of biomineralization in animals.
