Current Research

My doctoral dissertation investigated navigational and orientation strategies of the BaYaka hunter-gatherers in the Republic of Congo  during daily search for food in the forest. Using semi-structured interviews, systematic observations, and tools from social network analysis, my postdoctoral research examines foraging group dynamics, childcare and food sharing among the BaYaka women to investigate linkage between cooperative foraging and cooperative childcare in human subsistence decision making. I work in a close collaboration with Dr. Adam Boyette
