The 7th PhD Colloquium is an event of the System Dynamics Student Chapter. The objective of the colloquium is to bring together PhD students working on foundations, techniques, tools, and application of System Dynamics in a variety of disciplines and to give them the opportunity to present and discuss their research in a constructive and international atmosphere. Plenary presentations allow for common problems encountered by PhD researchers using System Dynamics to be identified. Each presentation will be followed by an extended discussion session , providing a unique opportunity for learning among all attendants. Combined with a poster session scheduled in the afternoon, we expect the all-day colloquium to be an exciting event. SD PhD Colloquium
