Transdisciplinary research offers a powerful approach to tackling complex challenges in natural hazards and risk management, but it also presents unique challenges, particularly for early career scientists and practitioners. This short course is specifically designed to equip early career participants with practical tools and strategies for effectively engaging in and contributing to transdisciplinary projects. By focusing on the cross-fertilisation of hard and social sciences, the course will provide actionable insights into how to communicate across disciplines, deliver impactful research, and find common ground for collaboration. Participants will engage in hands-on activities and discussions, drawing from the experiences of leading projects such as The HuT (https://thehut-nexus.eu), PARATUS (https://www.paratus-project.eu), MYRIAD (https://www.myriadproject.eu), and DIRECTED (https://directedproject.eu). Attendees are also welcome to join the scientific session and splinter meeting that are part of this unified path, allowing them to choose between engaging in the entire programme or specific parts according to their interests.
