The IRTG 2290 colloquium is an invited lecture series sponsored by the DFG and part of the structured PhD program. IRTG2290 PhD students are encouraged to host speakers, i.e., identify
guests and coordinate a series of meetings between the guest and interested members, as well as arrange for technical support during the lecture. Guest lecturers, who are invited by HU and ANU
faculty and PhD student members, present a one-hour talk about their work followed by a question and answer session.
