City Complexity Science Group

Complex Systems is a term that emerges in many disciplines and domains and has many interpretations, implications and problems associated with it. Complexity Science is currently undergoing a rapid growth worldwide caused by the challenge to understand problems in areas such as neuroscience, communication and internet, transport networks, engineering, computing, safety-critical infrastructures, production and management processes, biology, genetics, sociology, global financial markets, legal systems, environment etc. Despite the diverse nature of such systems it has been found that many commonalities exist such as on issues of interactions among the components, organisation of measurement and decision / control structures, issues of structural evolution and interpretation of emergent properties.  The specific domain provides dominant features and characterise the nature of problems to be considered. 

The City Group on Complexity Science aims to develop the fundamentals of this challenging emerging area by establishing a symbiotic relationship between "hard" and "soft" systems, where the human is considered as an essential element in the functioning of the system. Establishing a common language between the contributing disciplines is critical in developing research collaborations. A series of interdisciplinary seminars is considered as an essential step in establishing a forum suitable to handle the trans-disciplinarity of the area and promote research collaborations. This initiative is supported by members of different Schools such as: School of Mathematics, Computer Science & Engineering, School of Arts & Social Sciences, The City Law School, Cass Business School and School of Health Sciences. 


The effort to bring together alternative aspects of complexity is supported by:
