Every year, a substantial number of new Associate Editors and Reviewers are invited to be part of CEB. It is often the initiative of Editors to call on colleagues they know and trust for their technical depth and reliability. However, the CEB very much appreciates also the proactive volunteering of individuals. If you are interested in participating in the review process, either as a Reviewer or as an Associate Editor, please insert all data concerning your position, institution and expertise. Editors will have access to a list of volunteers, and will recur to your help wherever it may be most appropriate.
