Workshops and meetings

In the News

  • Dr. Els Heinsalu has spoken on the Estonian national TV channel about Complex Systems and our research on econophysics and languages! The interview was hosted by the scientific program "Curiosity Excellence Center" ("Uudishimu tippkeskus") and is available online!

Position Openings

  • Position opening in our complex systems group based in Tallinn, Estonia, in the field of language dynamics, within the project "The Role of Learning in Language Competition" supported by the Estonian Research Council through grant PRG1059.
    The position can be for 1 to 3 years. The starting date is negotiable, with the possibility to start immediately.
    The aim of the project is to develop new language dynamics models that explore the social and the cognitive dimensions of language directly connected to learning processes. The candidate will work with the PI of the project, Dr. Marco Patriarca, Dr. Els Heinsalu, and the other collaborators of the complex systems group, who have been actively working on various problems of language dynamics in the last years.
    The applicant should hold a PhD in physics or mathematics and a strong interest in complex systems, in particular language dynamics. In order to apply for the position please send a CV with publication list and a recommendation letter (or have the letter directly sent) to:

    • Els Heinsalu (els DOT heinsalu AT kbfi DOT ee)

    • Marco Patriarca (marco DOT patriarca AT kbfi DOT ee)

In case of any questions feel free to write to the contacts above.
