L’UMR 7206 "Éco-Anthropologie" est une unité mixte de recherche (UMR) du Centre national de la recherche scientifique (CNRS), du Muséum national d’Histoire naturelle (MNHN) et de l’Université de Paris.
I am a behavioural biologist interested in the evolution, functions and mechanims of sociality. I mainly study social relationships and social processes in macaques in order to understand how and why they form and maintain relationships. I am also interested in social transmission of behaviour and parasites/pathogens, which is tightly linked to the evolution of sociality. Who transmit what to whom, when, how, according to which rules are all questions I am investigating. The structure of a society greatly influences the patterns of social transmission, but less studied is the other side of that coin, how transmission affects the structure and evolution of society.

Responsabilités hors unité
I am also an associate director of the Macaca Nigra Project (MNP https://www.macaca-nigra.org/), a research-conservation-education field project dedicated to the study and conservation of the crested macaques, one of the flagship species of North Sulawesi. Crested macaques are critically endangered due to continuous threats from human expanding population, habitat loss, and hunting.
Connecting the dots: linking host behaviour to parasite transmission and infection risk
As part of my previous JSPS postdoctoral project and in collaboration with Andrew MacIntosh & Munehiro Okamoto at Kyoto University Primate Research Institute, I use two non-pathogenic common pathogens of rhesus and Japanese macaques, the simian foamy virus SFV and the bacterium E. coli, as markers of contact between individuals through their expressed genetic diversity. I then contrast networks of strain sharing and similarity between individuals and networks of affiliation and aggression in order to determine transmission pathways and dynamics in more details.
The impact of parasitism on primate health and behaviour
As part of Andrew MacIntosh's on-going long-term project, I am also involved in two studies with students Zhihong Xu and Kenneth Keuk on the relationships between individual social position within their network and level of parasitism in a population of Japanese macaques living on the island of Koshima, in the south of Japan. Part of Kenneth Keuk's MSc study constituted my first postdoctoral research in collaboration with Cedric Sueur from the Department of Ecology, Physiology, Ethology at the CNRS and University of Strasbourg, France. Theoretically, highly social individuals are expected to encounter a more abundant and diverse parasite community than less social hosts and thus to exert stronger influence on the transmission of parasites through their social networks. Empirically though, a lot of variance still needs to be explained and we are working towards refining our understanding of the existing heterogeneity in social and infection patterns.
Social tolerance, social diversity and social complexity
I am studying links between social tolerance, social diversity and social complexity in a homogenous yet diverse primate genus, Macaca, in order to unravel the causes and consequences of social complexity. To this end, I so far gathered an exhaustive data set on social behaviour of macaques within a collaborative network of more than 50 studies from more than 30 researchers on at least 12 different macaque species. Analyses are on-going. Stay tune!
Terrains de recherche
I study two very social species of primates but with very different social styles, the Japanese Macaca fuscata and the crested macaques Macaca nigra. Both form large social bisexual multi-generational groups. The former is “despotic” with a strict hierarchy and a strong kin bias in social interactions leading to clustered social networks; the latter is “tolerant” with a less steep hierarchy and a weak kin bias leading to denser social networks. Crested macaques are studied as part of the Macaca Nigra Project in Sulawesi, Indonesia. The project is studying the biology of the species since 2006 (www.macaca-nigra.org). Japanese macaques are studied in Yakushima island and in Koshima island, in the south of Japan where they have been studied since the 1980s and 1950s respectively.
