International, national and institutional involvement:
I have been a member of GLOBEC (Global Ocean Ecosystem dynamics) Focus 1 Working Group on retrospective analysis and time series studies and I was involved in the GLOBEC-SPACC initiative (Small Pelagics and Climate Change).
I have been a member and chair of several expert groups at the International Council for the Exploration of the Sea (ICES). I am currently co-chairing the Working Group on International Deep Pelagic Surveys (WIDEEPS) and member of the Arctic Fisheries Working Group (AFWG).
I have been a member of the Sir Alister Hardy Foundation for Ocean Science (SAHFOS, UK) board of directors (2001-2005) and a member of the council as sponsoring governor of the foundation on behalf of fremer (2006-2007).
I have participated in the EU-projects TASC, SAP, UNCOVER, RECLAIM and DEEPFISHMAN.
I have been part of the Marine Ecology Progress Series board of review editors (1998-2005) and was associate editor for Fisheries Oceanography (2007-2010). I have refereed more than 250 manuscripts and proposals.
