An 'Ordinary' seminar - organised on Wednesdays by either the IDM, or once a month by the Department of Immunology (2 speakers, often postgrad students or postdocs).
A 'Special seminar' - presented by a visiting specialist on a separate weekday.
An IDM S3 seminar (Science, Snacks, Social) - with a more informal 5 minute introduction by the Chair interacting with the speaker, asking questions of the speaker on a more personal level (to get to know them more, how they progressed in their career etc.); snacks provided afterwards to facilitate attendee interaction.
An IDM Juxtaposition seminar - a double speaker seminar where the topic is on two seemingly diverse areas of knowledge around the same issue, with the aim to foster new ideas.
