You might be interested to note that UKRO has set up a page listing all the ongoing EU consultations related to Horizon 2020, including the preparation of future work programmes, the interim evaluation of H2020 and developments related to the next framework programme such as the creation of the European Innovation Council.
There are currently a number of ongoing consultations on the next work programmes for different parts of H2020. These are good opportunities to feed in your ideas and shape the future content of work programmes and specific calls for proposals. You can find these listed here but will need an UKRO account to access this page.
As we are a subscribing organisation, any Northumbria colleague can set up an UKRO account which will enable you to receive daily update emails on EU funding opportunities, events, and policy developmens relevant to UK-based academics.
