Research Interests

As a physical geographer, I am interested in the study of human-environment interactions using a multidisciplinary, spatial approach. Specifically, I have used geographic information systems (GIS), remote sensing, and statistical analyses to study land cover/land use change, coastal and watershed erosion, and water quality degradation, all relevant themes to understanding environmental change and assessing the long-term sustainability of human activities.

Current Research

Currently I am working on the conceptual design, data loading and maintenance of a geodatabase that includes detailed field geological data for Eastern Panama and the Canal area. Eventually, these data will be interpreted as geological maps and will include valuable information on structures, geochronology and biostratigraphy. I am also participating in a project that deals with paleogeographic reconstructions in northern Colombia, using the software GPlates. The purpose of this project is to recreate the movement of geological blocks at different time steps.
