Research Interests

 My research program lies within the field of geographic information systems and remote sensing as applied to conservation science. My work focuses on developing tools to assess: a) ecosystem extent and disturbance dynamics, and b) plant-animal interactions in a landscape. Both lines of research seek conceptual and methodological contributions in the way ecosystem processes are mapped, studied and monitored. More information in my Lab's website.
