Research interests

My research belongs to the field of ethnomathematics and is guided by the following question : How is an activity recognized as "mathematical" when it is not identified as such by those who practice it ? The aim of my work is to study the mathematical rationality that underlies activities involving geometrical and algorithmic practices (such as string figure-making or sand-drawing in Oceania), while attempting to analyze how the practitioners of these activities conceive - or have conceived - them in societies of oral tradition.

This study is based on three main directions of research :

  • I carry out ethnographic research in Oceania (Marquesas Islands, Papua New Guinea and Vanuatu) and in South America (Paraguayan Chaco) to collect local corpora related to these activities, while seeking to understand in situ the contexts of production and use of these mathematical practices.
  • I develop mathematical modeling in an attempt to reconstruct the processes through which the actors from different oral tradition societies have explored the making of string figure algorithms and other artifacts.
  • I carry out an epistemological research on the forms of rationality that underlie the creation of the algorithms involved in string figure-making and other geometrical practices.
