My main interest is the evolutionary origins of major
vertebrate taxa. I am currently studying paleozoic temnospondyl amphibians
in order to figure out some of the controversies hampering our understanding
of modern amphibian groups. Whereas the evolution of some vertebrate classes,
such as birds and mammals, is relatively well known, the origins of the
extant amphibian orders (frogs salamanders and caecilians) remain controversial.
More specifically, my studies focus on the Lower Permian amphibian genus
Doleserpeton, which may be linked to the origins of modern frogs.
