Summary

I was born in Costa Rica and I obtained my Bachelor degree in Biology at the Universidad de Costa Rica (UCR), San José, Costa Rica in 1999. I obtained my Master degree in Plant Ecology at the same university in 2002. At  2010 I received my Doctoral degree from Universidad Nacional Autónoma de México (UNAM), México. I was postdoctoral researcher from 2011 to 2015 at the Pontifícia Universidade Católica do Rio Grande do Sul (PUCRS). In my research I studied the role of Neotropical primates on the forest  regeneration and the influence of forest fragmentation and climatic variables on their behavioral flexibility . The major results of my research was published in American Journal of Primatology, Plos One, and Biotropica.
