Roland Sookias

I have just completed a PhD with the Archosauromorph Research Group reassessing the monophyly, anatomy and distribution of the early archosauromorph group 'Euparkeriidae'.

I will begin a two year postdoctoral research position at the Museum für Naturkunde, Berlin, with Prof. Dr. Johannes Müller in September 2016.
