I lead a lab in LB-144. My research focuses on large mammals ecology (population parameters and movement) as umbrella species to protect the last strongholds within indigenous and afro-descendant territories in the Caribbean coast of Nicaragua. Little is known about the large mammals' population in Nicaragua such as Baird's tapir and jaguars. These endangered species are declining, and research and conservation efforts are paramount to preserve those species in Nicaragua.

I run a project to help preserve Bairds tapirs in Southeast Nicaragua.

The Nicaraguan tapir project focuses on three main components:
  • Tapirs and their interaction with their ecosystem: this component aims to understand the population parameter of the species, its interactions with the ecosystems, humans, and threats.
  • Communities and Conservation: aims to work with local communities to develop protection and sustainable alternatives to preserve tapir habitat and communal land.
  • Communication for conservation: aims to develop awareness and educational campaigns for tapir conservation in indigenous territories.
