What are the most acute threats to nuclear security and how are they evolving? How does nuclear security relate to non-proliferation and disarmament? In this episode we talk to Lars van Dassen, who is executive director of the World Institute for Nuclear Security (WINS) in Vienna.

This episode is presented in collaboration with the Alva Myrdal Centre for nuclear disarmament.

In this episode we discuss the Iranian nuclear issue with Ambassador Stephan Klement, who is the EU Special Envoy for Disarmament and Non-Proliferation.

He has been a part of the nuclear negotiations with Iran for more than 20 years and is a Special Advisor for the Iranian nuclear issue in the European External Action Service.

Since Stephan holds two doctoral degrees, in International Law and in Physics, we also zoom in on the interdisciplinary aspect.

In this episode, Karen Brounéus, professor in peace and conflict research and clinical psychologist, takes us on a journey from grassroots work to the bird's-eye view of research and policy and back again. Karen’s research helps us think more deeply about the intrinsic link between mental health and conflict reduction.

Her new Uppsala Initiative for Global Mental Health and Peace includes a project in Tigray, Ethiopia, developing an evidence-based approach to treat post-war depression, and a project with Mindfulness-based stress reduction in Sweden.

In this episode UCDP Research coordinator Therese Pettersson discusses their newly released data for the year 2024. She also walks us through how the Uppsala Conflict Data Program ensures the quality of the datasets and how they tacke key challenges in data collection.

A special data feature in which the UCDP team discusses the data is available open access on the Journal of Peace Research website.

We also recommend the latest episode of PRIO's Peace in a Pod, which asks what the rise in global conflict means for children in the affected areas.

This special episode features the talk by Professor Mary Ellen O’Connell from the Kroc Institute for International Peace Studies, which she gave at the inaugural Peter Wallensteen Lecture on 20 May 2025 in Uppsala. This new lecture series honours our founder Professor Peter Wallensteen.

The talk begins with a critique of the current reliance on deterrence theory. Professor O’Connell then proceeds to argue how AI research and state funds should be reoriented from deterrence towards self-defence based on the principles of international law. We found the talk thought-provoking and hope you too will find it stimulating!

Mary Ellen O’Connell is the Robert and Marion Short Professor of Law and Professor of International Peace Studies—Kroc Institute for International Peace Studies at the University of Notre Dame, USA. Her work is in the areas of international law on the use of force, international dispute resolution, and international legal theory. Her current work is on AI in the military domain.

After several decades of relative stability, many now question the health of the global nuclear order. In this episode, Dr. Stephen Herzog offers his take on the impact of the Russian war in Ukraine, the rise of China, and recent shifts in US foreign policy under Trump. Is the nuclear taboo eroding? Will more countries acquire nuclear weapons? Are key non-proliferation and disarmament treaties under threat? Stephen has done extensive research on these topics and published many influential papers. In fact, we were so impressed with his thorough, innovative, and surprisingly optimistic analysis that we decided to make this an extended episode!

Dr. Stephen Herzog is Professor of the Practice at the James Martin Center for Nonproliferation Studies, based at the Middlebury Institute of International Studies at Monterey. He is the Academic Co-Chair of the Harvard-MacArthur Foundation Beyond Nuclear Deterrence Working Group. Professor Herzog has been involved with the Alva Myrdal Centre's Working Group 1 on Nuclear Negotiations since it began and is a frequent guest lecturer for the AMC's academic programming for students at Uppsala University. He has published widely in scholarly and policy journals and holds a PhD In Political Science from Yale University. Before returning to academia, Dr. Herzog was a nuclear arms control official working for the US Department of Energy.

This episode is produced in cooperation with the Alva Myrdal Centre for Nuclear Disarmament. It is hosted by Communications Officer Joakim Palmén.

In this episode, Johan Brosché helps us navigate the complexities and horrors of the civil war currently raging in Sudan. Johan works as associate professor at our department and is one of Sweden’s leading experts on Sudan.

A quick glance at Johan’s CV reveals his academic interest in Sudan, but during our conversation his engagement and empathy for the people of Sudan also became apparent.

During our conversation Johan shared memories from Sudan and recent reports from contacts on the ground, while offering valuable insights into the conflict , paths towards de-escalation and why the war is underreported in Western media.
