Faculty Profile


Originally from El Salvador, I moved to Costa Rica where I completed my biology degree at the School of Biology, University of Costa Rica. After my B.Sc. and motivated by the ecology and evolution of reptiles, I worked as a coordinator assistant of the population monitoring of a sea turtle project on the Pacific coast of Costa Rica. In 1989, I began a Master degree at the University of Oxford, where I studied behavioral ecology of mixed-species flocks.

After my master degree, I returned to Costa Rica to work as a research director for the Monteverde Conservation League. There I coordinated and administered several conservation projects, including the conservation of forest fragments and watersheds in farms. After 6 years of conservation work, I began my doctoral research on the effects of forest fragmentation on bird species in the premontane forest of Monteverde. The combined experience gained in conservation and ecology led me to initiate my work with SFS as a Natural Resources Management lecturer. I am currently the Tropical Ecology lecturer. My research interests revolve around the behavioral ecology of vertebrates and the conservation issues that affect them. My main focus is on the effect of road traffic on vertebrates. This includes road kills and the bio-acoustic of the birds exposed to traffic noise. I am also interested in landscape ecology as a tool for conservation strategies in the tropics.

Research Projects


The research conducted at SFS field stations is designed to answer key questions related to critical and related social and environmental problems and to provide our hosts with detailed and accurate information for decision making and action. Faculty and student research projects are linked to the Center’s Five-Year Research Plan, which defines an overarching research directive.

This project studies the diversity of bird vocalizations influenced by traffic noise in Carara, Poas and Santa Rosa National Parks. We use point counts and records of bird vocalizations to determine species richness in relation to road proximity.

This project looked at the frequency of roadkills along the Coastal Highway adjacent to Carara National Park. We conducted 2 to 4 surveys a month during 2010-2011 in 4 km of the Highway bordering the park. The highest mortality was in the amphibian group followed by reptiles, mammals and birds.
