ResearchPrimates Peru is a project based on the dissertation field research of Mrinalini Watsa, and is affiliated with Washington University in Saint Louis.
The project will focus on a previously unstudied population of saddle-back tamarins (Saguinus fuscicollis) in south-east Peru, at a state-of-the-art biological field station (CICRA) on the Río Madre de Díos. 
The focus of the project is two-fold:
1. The acquisition of suitable genetic material from subgroups within the tamarin population
2. Observation of behavior in the context of reproduction, infant care and alloparenting.
