About the centre

Understanding how living organisms respond and adapt to environmental changes remains a major and urgent scientific challenge. The Centre for Ecological and Evolutionary Synthesis (CEES) combines a broad spectrum of disciplines – such as population biology, statistical and mathematical modelling, and genomics – to foster the concept of ecology as a driving force of evolution via selective processes, with a corresponding influence of evolutionary changes on ecology.


CEES was established as a Norwegian Centre of Excellence (CoE) at the Department of Biosciences in 2007. The 10 year CoE period ended in October 2017, but CEES continues as a centre and section at the Department beyond 2017. Through the years 2007-2017 the CoE funding from RCN constituted approximately 1/10 of the total budget. CEES was Chaired by Professor Nils Chr. Stenseth until September 2018. CEES is now Chaired by Professor Kjetill S. Jakobsen.

Social media


CEES consists of over 140 members (including Core staff, Postdocs and researchers, PhDs, research assistants, technical and administrative staff, and Master’s students). In addition we have many short and long time guest researchers. The members and guests represents over 25 nationalities.

Open seminars

An important goal of CEES is to communicate its research and findings, as well as to increase the appreciation and understanding of science. Our aim is to reach both Norwegian and international audiences. A central part of our scientific outreach is the open seminars with high-profile researchers and communicators of science.
