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.  


Stepney, Susan

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.

Upcoming events

Summer Seminar Series to be advertised shortly

Fridays at 13:30 in RCH/204




  • Two PhD studentships - see YCCSA Opportunities to join our team of researchers working on the Spinspired reasearch project funed by EPSRC and the Univesity of York.  An interdiciplinary collaboration between researchers from York’s Departments of Computer Science, Electronic Engineering, and Chemistry, and the York Cross-disciplinary Centre for Systems Analysis (YCCSA).
  • Registration open for YCCSA's TWCR 2018! Evolution, Evolvability and Change - First International TRANSIT workshop on Cross-disciplinary Research,  on 11-12 April 2018 at the Ron Cooke Hub
  • Professor Susan Stepney - will be on a panel debating Artificial Life at the Science Museum, Wed 28 March.
  • Professor Reidun Twarock - has been awarded and EPSRC Established Career Fellowship to work on the project "Geometry as a key to the virosphere: Unmasking the fundamental roles of geometry in virus structure, evolution and pathology'
  • Published - Cuesta, J. A., Delius, G. W. and Law, R. 2018. Sheldon spectrum and the plankton paradox: two sides of the same coin – a trait-based plankton size-spectrum model. Journal of Mathematical Biology76:67-96
  • YCCSA Summer School Scholarship Programme - Applications are now open, closing date noon 9 March
  • YCCSA has changed its name (but not its acronym) to better reflect our core research identity and focus.  We are now: York Cross-disciplinary Centre for Systems AnalysisThis does not represent a change in direction: we will still be focused on "complex systems" research.  It is rather tracking the way the use of terminology is changing in the wider world.  It brings to the fore our cross-disciplinary nature, which has always been a core part of our being, as established during the EPSRC TRANSIT project and continuing with the annual YCCSA Summer School and new workshop series.  
  • Just published - Inspired by Nature - Essays presented to Julian F Miller, Editors Susan Stepney and Andy Adamatzky
