Research
I obtained PhD in biology in 2013. The field of my PhD research was analysis of the archosaur fossils from the Late Triassic of Poland. My recent studies are based on Permian, Triassic and Jurassic fossils collected during fieldworks in Poland (2001-2017), Russia (2008, 2010, 2013), Tunisia (2008, 2013), Greenland (2014, 2015, 2016), Sweden (2015, 2016, 2017) and also analysis of other specimens housed in museums and collections in Poland, Russia and Sweden. Recently, I decided to apply my skills to novel research questions, and I find challenging big questions, like the palaeoichnological record of early tetrapods and evolution of early dinosaurs, especially inspiring.
