We welcome registrations from PhD students, where the student is pursuing a programme of research for which the COW will provide intellectual benefit and/or from whom the workshop and its other attendees will gain benefit. We do not normally expect to register students other than those on PhD level programmes of study. For example, those students taking a course at the equivalent of UK masters or bachelors level would not, ordinarily, be considered eligible to register for COW. However, we are willing to consider exceptional cases, where a masters or bachelors student has a clear contribution to make to the topic of the COW. In all cases, students must have the approval of their supervisor/advisor for their attendance at the COW and his or her consent to the terms of registration. This is why we ask that students seeking to register for a COW also supply the contact details of their supervisor.
