Responsabilités dans l'unité

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. 

  • costs and benefits of sociality
  • social complexity and dynamics
  • social cognition

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.

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, in collaboration with Muhammad Agil and Dyah Perwiasarih-Farajallah from IPB University, Bogor, 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, in collaboration with Andrew MacIntosh from the Kyoto University Wildlife Research Center.
