DTU Compute’s Sections for Cognitive Systems, would like to invite applications for a 2-year postdoc position starting 1January 2021. The project is financed by the Carlsberg Semper Ardens project HOPE. The researcher will be supervised by Professor Sune Lehmann at the Section for Cognitive Systems, DTU Compute, but also associated with SODAS at the University of Copenhagen. 

The Cognitive Systems Section at DTU:
Advanced data analysis is increasingly a determinant for productivity and personal quality of life. The Section for Cognitive Systems researches information processing in man and computer, with a particular focus on the signals they exchange – audio, imagery, behavior – and the opportunities these signals offer for modeling and prediction. Our research is based on statistical machine learning and signal processing, on quantitative analysis of digital media and text, on mobility and complex networks, and on cognitive psychology.

Center for Social Data Science (SODAS) at University of Copenhagen:
New types of data, in particular digital data, is flooding the social sciences. The broad catchphrase for the analysis of such data is ‘data science’. The Faculty of Social Sciences has made new, digital forms of data – sometimes collectively known as big data – and the integration of such data with social scientific modes of enquiry a priority at the Faculty. We call this integration Social Data Science, with research carried out in an inter-departmental center comprising researchers from across the social sciences.

Project Description
The How Democracies Cope with Covid19: A Data-Driven Approach (HOPE) project constitutes an unprecedented research project which examines the interrelationship between the (a) trajectory of the COVID-19, (b) the decisions of governments and international organisations, (c) media and social media landscapes and (d) citizens’ behavior and well-being.

To this end, we utilize the fact that the COVID-19 pandemic is unfolding in the middle of the “big data” revolution. For the first time in human history, we are able to measure with extreme precision and time-resolution how governments and citizens react (and with what consequences) during an extremely severe crisis.  

This PostDoc Project supports the overall HOPE project by analyzing large-scale data on the COVID-19 crisis, focusing on telecommunication, social media data, and human mobility data. The researcher will integrate with other branches of the HOPE project to understand the connection between these large-scale behavioral data and questionnaire data or anthropological field studies.

Responsibilities and tasks
The successful applicant will

  • Analyze and model structures in large scale data, including mobility data collected from mobile phones, and social media data.
  • Collaborate with researchers from both computational and social sciences in a truly interdisciplinary environment.
  • Co-author scientific papers aimed at high-impact journals
  • Participate in international conferences.


  • You should have a PhD degree or equivalent.
  • You must have a background within physics, applied mathematics, machine learning, computational social science, or related fields. 
  • A track record of publishing interesting work within some of those fields.
  • Experience analyzing large-scale datasets in Python.
  • Experience with machine learning (incl) deep learning for prediction problems.
  • Broader experience with programming is an advantage.
  • Experience in time-series analysis is an advantage. 
  • Experience with modeling complex networks or human mobility is an advantage.
  • Experience in Spark is an advantage.
  • An active interest in strong collaborations and interdisciplinary work is a plus.
  • An active interest in communicating science is a plus

We offer
