International Graduate School Programs

Doctoral research is, almost by definition, a solitary endeavour. A PhD candidate spends three to five years going deeper into a narrower topic than anyone around them can easily follow. The AC21 International Graduate School (IGS) was designed to counter that isolation — not by turning doctoral work into a group activity, but by placing PhD candidates in an international, interdisciplinary environment where their work could be challenged and enriched by perspectives they would not encounter at their home institution.

The IGS ran from 2010 to 2021, with sessions hosted by AC21 member universities on a rotating basis. Each session lasted seven to ten days and focused on a specific research theme, chosen for its relevance across multiple disciplines and its alignment with the research strengths of the host institution.

Structure and Approach

What distinguished the IGS from conventional summer schools was its emphasis on active research over passive instruction. Participants did not sit through lecture series. Instead, they arrived with a prepared research proposal related to the session's theme and spent the week working with assigned faculty supervisors from the host university. Mornings were typically devoted to methodological workshops; afternoons to supervised research work and peer review sessions.

Each session concluded with a symposium where participants presented their work to the full cohort and a panel of faculty from multiple member institutions. The feedback was substantive. We have spoken with former participants who described the final presentation as the most rigorous academic experience of their doctoral career — more demanding, in some cases, than their eventual thesis defence.

The programme attracted 15 to 25 participants per session, drawn from across the consortium. Selection was competitive: each member university could nominate up to three candidates, and a committee evaluated proposals on originality, methodological soundness, and the potential for cross-disciplinary engagement.

Themes and Host Institutions

Session themes reflected the research priorities of host institutions. Nagoya University hosted sessions on materials science and automotive engineering. The University of Freiburg focused on sustainability and renewable energy. Adelaide ran a session on water resources and arid-zone ecology. The University of Strasbourg hosted a session on European governance and transnational policy. NC State's session addressed data science and precision agriculture.

The interdisciplinary nature of the programme was deliberate. A session on "Smart Cities" hosted by Tongji University in 2017, for instance, brought together doctoral candidates from urban planning, electrical engineering, sociology, and public health. The resulting cross-pollination produced several co-authored papers and, in at least two cases, led to joint supervision arrangements between faculty at different member institutions.

Connection to Other AC21 Programmes

The IGS did not operate in isolation. Many participants had previously attended the Student World Forum as undergraduates or master's students. The progression from SWF to IGS was informal but real: roughly 15% of IGS participants over the programme's lifetime were SWF alumni, according to secretariat records.

Faculty involved in the IGS also drew on research funding from the Special Project Fund to support follow-up collaborations with IGS participants. In several instances, an SPF grant was used to fund a return visit by a doctoral candidate to the institution where they had attended an IGS session, allowing them to complete experiments or data collection that had begun during the programme.

The International Forum also provided a venue for IGS alumni to present their research at a more senior level, reinforcing the consortium's intent to create a continuous pipeline from student exchange to established academic partnership.

Graduate Research Opportunities Today

For doctoral candidates seeking comparable international research experiences, several pathways exist. The FindAPhD platform maintains a comprehensive database of doctoral opportunities, including short research programmes and funded mobility schemes. The DAAD (German Academic Exchange Service) offers structured programmes for international doctoral researchers, including short-term grants for research stays at German universities. Networks like the Worldwide Universities Network and the Guild of European Research-Intensive Universities operate their own graduate mobility programmes with structures not unlike the AC21 IGS.
