RESEARCH FOCUS

We live in a world more complex, interdependent, and entangled than at any point in human history, from the impact of pollution and environmental degradation on public health to our shifting health and social care systems. Yet our sciences still struggle to confront these challenges in a truly transdisciplinary way.

Hence the focus of my work. Over the past twenty years I have explored the intersection of the complexity sciences, interdisciplinary methods, visual arts and public policy to forge new ways of making sense of – and responding to – the complex global and local social systems in which we live.

This journey culminated in The Atlas of Social Complexity – which my colleague Lasse Gerrits and I spent five years researching and writing – and the field of case-based complexity, which my colleagues and I developed.

 

THE ATLAS OF SOCIAL COMPLEXITY

THE ATLAS charts the bold, disruptive journeys of scholars reshaping the study of social complexity into a force for impactful change through transdisciplinary engagement. They begin with the thirteen situations – the methodological, epistemic, and institutional conditions that social complexity research must navigate, and which too often blunt its disruptive potential. These include the need for methodological pluralism, bridging disciplinary silos, addressing issues of scale, and engaging stakeholders. 

As a corrective, they cultivate a social complexity imagination – a way of seeing, thinking, and acting rooted in the lived, entangled realities of our social, ecological, and technological systems – and advance a social science turn in complexity, which directly engages with inequality, power, identity, and the messy histories in which systems are embedded. Across the Atlas, we follow these researchers as they confront the thirteen situations in various combinations and with varying degrees of success, from the self and mind to urban planning and global economics. But the Atlas does not stop at science. Across its pages runs a second throughline: the visual arts and humanities as modes of social complexity inquiry. Here we follow a growing network of artists and philosophers whose practices offer new ways to see and embody social complexity.

 

CASE-BASED COMPLEXITY

Case-based complexity treats cases — whether individuals, groups, organisations, or places — as the primary unit for understanding complex social systems, focusing on the configurations of factors that shape their outcomes and the clustering of trajectories through which their lives and histories unfold.

My colleagues and I have developed a suite of methods. At the computational end is COMPLEX-IT, which combines self-organising maps, clustering, and network analysis into a user-friendly platform for non-experts, enabling researchers and policymakers to explore patterns and trajectories in social systems. At the artistic end is case-based visual complexity, where my work, for example, with tangles transforms these ideas into images, sculptures, and installations that materialise entanglement in ways data alone cannot.

Together, these methods show how case-based complexity can move fluidly between the sciences and the arts. Taken together, this dual trajectory of computational modelling and visual arts practice demonstrates how case-based complexity can operate across disciplines, speaking to both the sciences and the humanities.
