Annual Conference 2025
29 September 2025 in Vienna (Austria)
Complex Systems: Shaping the Future for a Resilient Society
Austrian Academy of Sciences, ÖAW
Vienna, Austria, September 29, 2025
Real-world systems – whether environmental, societal or technological – are inherently complex. They involve nonlinear interactions, feedback loops, delays, and emergent behaviors that challenge traditional, siloed approaches. Our goal is to explore how we can better understand and manage these systems to increase societal resilience.
ADDRESS TODAY’S MOST PRESSING CHALLENGES
From climate instability to healthcare system shocks and energy transitions – modern problems are deeply interconnected. This symposium tackles these challenges through the lens of complex systems, offering new ways to understand and act on them.
Complex problems don’t fit neatly into disciplines. This event brings together voices from science, engineering, policy and society to build cross-disciplinary insights and solutions, encouraging new connections that mirror the interwoven nature of the challenges we face.
EXPLORE HIGH-LEVEL, ACTIONABLE IDEAS
We’re not just dissecting problems – we’re imagining bold, conceptual strategies that can lead to real-world impact. Expect big-picture thinking grounded in practical applications.
BUILD A MORE RESILIENT FUTURE
Learn how resilience can be designed into systems – from ecosystems to infrastructure – and how that mindset can help society adapt and thrive amidst uncertainty.
CONNECT, COLLABORATE AND INNOVATE
Meet leading thinkers, practitioners and change-makers. This is a unique opportunity to form meaningful partnerships and spark innovative projects that extend well beyond the symposium.

CARLO RATTI
MIT Massachusetts Institute of Technology
The way we live, work, and play is very different today than it was just a few decades ago, thanks in large part to a network of connectivity that now encompasses most people on the planet. In a similar way, today we are at the beginning of a new technological revolution: the Internet is entering the physical space – the traditional domain of architecture and design – becoming an “Internet of Things” or IoT. As such, it is opening the door to a variety of applications that – in a similar way to what happened with the first wave of the Internet – can encompass many domains: from production to citizen participation, from energy to mobility to public hygiene, all of which requiring new insights due to the changes brought forth by the ongoing COVID-19 pandemic. The contribution from Prof. Carlo Ratti will address these issues from a critical point of view through projects by the Senseable City Laboratory, a research initiative at the Massachusetts Institute of Technology, and the design office Carlo Ratti Associati.
