Copenhagen Causality Lab (CoCaLa)

We do research on causality, statistical modelling, and data analysis.

You can find us at the Department of Mathematical Sciences, University of Copenhagen and converse with us on matrix – just join #lobby:ucph.ems.host via the open network for secure, decentralized, cross-institutional communication.

Please reach out to us when you are interested in joining or working with us! Positions are announced via the department’s calls. The annual PhD calls have deadlines in April and November. The annual postdoc call opens in October with a deadline in November.
