The individual PhD research projects form the core of the doctoral programme.

They are each supervised by one of the Principal Investigators of BioToP, however, close collaboration with other research groups/PIs within this doctoral program is foreseen. This will thus strengthen the multi-disciplinary character of this programme.

In addition, short term research stays abroad (approx. 6 months) in the laboratories of international collaboration partners are planned.

Below you can find a list of all PhD projects. Use the drop-down menu to select projects from the different research areas or individual Principal Investigators.
