The objective of this splinter meeting will be to to discuss some of the challenges related to working at the science-policy-practice interface. The focus of the discussion will be on the process of working at this interface and we hope will draw on the experiences of those present so that participants might share their own stories, what worked well for them, what didn't, etc. The meeting will be targetted at a wider audience than just the participants of individual NH sessions at the conference as other sessions are also discussing the relationship between science and policy making.
