ABOUT
I am a palaeontologist, specialised in dinosaur palaeobiology. To understand the biology and evolution of these animals, careful study of their fossil remains is required. I have been studying bone, tooth and eggshell tissues of fossil and extant tetrapods since 2007. During my PhD, I studied the effects of gigantism on the structure of sauropodomorph bone tissues. Since then, I developed histomorphometry and comparative histological methods to characterise and compare different mineralised tissues of various tetrapods, including dinosaurs and other reptiles, but also mammals and amphibians.
