My research uses population genetics to better understand human evolutionary history, including adaptation, genetic demography and archaic introgression. I am interested in how large-scale patterns of genetic variation, over countries and continents, are impacted by local social behaviours such as kinship practices, migration and movement decisions, and social hierarchies. I combine modelling and simulation with information from human genetics and other sources (linguistics, movement ecology, ancient DNA, domesticate genetics and the microbiome) to better understand these processes. My work has a regional focus in South Asia and island Southeast Asia.



  • Human evolutionary genetics
  • Social behaviour and genetic diversity
  • Non-human and the microbiome
  • Hunter-gatherer genetic variation

I am presently involved in the following research projects:

  • 2018-2020: Archaic introgression and the evolution of modern humans
  • 2018-2020: Borneo Human Genome and Microbiome Diversity in Association with Health and Disease
  • 2019-2021: Pilot study of Cave Punan hunter-gatherers of Borneo
