SHAPE ENERGY has made it one of its priorities to include activities focussed on fostering interdisciplinarity and to facilitate reflection on the outcomes of this. The SHAPE ENERGY Reflexive Review of Interdisciplinary Working presents these outcomes with regard to three overarching methodologies applied in SHAPE ENERGY: (i) an academic literature review; (ii) a set of ethnographic observations of interdisciplinary interactions, and (iii) the method of ‘reference problems’ which brings together scholars around commonly shared scientific problems.
