I started my academic career as a modeller (in fact, as an artificial life/robotics researcher: this is my first publication ever), and I continue to believe that computational models are a fundamental tool to develop research in cultural evolution. On the one hand, models are excellent theory-generating machines: they allow you to formalise your thought experiments, and to explore their consequences, which is sometimes impossible by intuition alone. On the other, models make your theories explicit and directly testable by other researchers. Recent topics include whether cultural stability can be obtained without copying or selection (yes), whether conformity can be detected from population-level effects (not always), or how redundancy can contribute to cultural stabilization. I am also particularly interested in the opportunities offered by tools like Git or R Markdown to document step-by-step the development of models, as I am currently doing here.
