The seminar series is aimed to be informal by default, which allows for the variation of polished presentations right down to general chat. In many years we have set a theme of presentations built around a text, major research article or topic, with only occasional presentations of general research. Over the years this style has become less frequent, with most seminars on recent research performed within the group.
