Archäoforum: Michael Müller cand. Phd (DE)
I am a PhD candidate at the Institute of Prehistory at the FU Berlin. My research interests are the Neolithic and Chalcolithic periods in Europe and I focus especially on anthropomorphic representations and hoards. For my master thesis I worked on Neolithic and Chalcolithic anthropomorphic figurines from Southeastern Europe. For my PhD, I am investigating the depositions of the Funnelbeaker culture, particularly those with flint axe heads. In connection to that I started to do some experimental work with flint knapping and grinding of axe heads.
