YCCSA is a community of researchers drawn from different departments developing novel mathematical, computational and analytical methods and tools for the analysis and modelling of complex systems.

Professor Susan Stepney
YCCSA Director

Welcome to YCCSA.  We are an open community of cross-disciplinary researchers, drawn from a diverse range of departments across the University at York.  We are working together, developing and applying novel methods and tools to analyse, model, explore, and solve complex problems that cannot be tackled by one discipline alone.

Some 70 YCCSA staff and research students are co-located in purpose-built dedicated research space in the Ron Cooke Hub on the new Heslington East campus.  Other YCCSA members reside in their home departments, and are very much part of the YCCSA community.

As well as carrying out cross-disciplinary research, we also reflect on the process itself, and develop new ways to help bring researchers together and bridge the gaps between disciplines.  We each bring our own different and valuable perspectives to the challenges of researching complex systems.

Do browse our site to find out more about our people, our past and current research projects, and our engagement activities and events.

Research Themes

YCCSA's research takes three broad themes within the realm of complex systems research:
  • Resilient and Adaptive Systems
  • Biomedical and Ecological Systems
  • Natural Computation and Engineering

Featured research

IGGI Project: Intelligent Games and Games Intelligence

The EPSRC Centre for Doctoral Training Intelligent Games and Games Intelligence (IGGI) is a collaboration between the University of York, the University of Essex and Goldsmiths College, University of London. It will train the next generation of researchers, designers, developers and entrepreneurs in digital games. The doctoral programme combines practical skills training with advanced teaching in cutting-edge research topics and the chance to contribute original research to a growing academic area.
