Research collaborators

Collaboration between the Degrees Modelling Fund (DMF) research teams and experienced SRM modelling scientists is a crucial part of the DMF research process. While the DMF scientists are experts in modelling the local impacts of climate change, few have worked on SRM before. Each team is paired up with at least one SRM modelling expert and they work together remotely over the duration of the project. Research collaborators volunteer their time and the relationship is intended to be mutually beneficial to both collaborator and the DMF team.
