ACADEMIC FIELD & RESEARCH
I study the development and mother-child relationships of wild chimpanzees. I have previously focused on observing foraging behaviors, but my current interest is the development process of excretion behavior.

I want to deepen my thinking about the evolution of humans through research meetings.
