Apologies for longish absence here.
Now for the question of Bio- in The Institute for Geo and Bio-Archaeology. The short answer is: the bioarchaeology component is, effectively, non-existent. You might be hoping that you will be able to find your own field project and, hey, things will work out somehow in the end. DO NOT harbor such innocent views. Neither will you have an opportunity to learn about micromorphology or organic residue analysis in a taught course. There is little to no interest amongst the teaching staff in the organic archaeological materials.
Do not expect constructive advice. Do not expect interest in your ideas.
If you are passionate about bioarchaeology do not waste your valuable time by becoming a graduate student at the VU.
