The European Commission has published a call for independent experts to evaluate proposals for EU funding under HORIZON 2020, and also for other activities like monitoring, programme evaluation and policy development. See the press release: http://ec.europa.eu/research/index.cfm?pg=newsalert&year=2013&na=na-221113
We encourage expert mathematicians to apply. For that one should have to go first to the participant portal http://ec.europa.eu/research/participants/portal/page/home and create an account.
The call remains open for the lifetime of HORIZON 2020. We will appreciate your collaboration in the distribution of this information.
With best regards,
President The European Mathematical Society
