Research

My current research interests are in the following domains:

  1. The development of research methodologies of a computational nature for social science problems, in particular in behavioural science research.
  2. The use of causal machine learning combined with experiments in behavioural and social sciences.
  3. Applications of evolutionary thinking in the social sciences.
