    My scientific research interests are in landscape ecology and disturbance mapping within the boreal forests of North America. I utilize GIS and Remote Sensing to understand aspects of the disturbance regime, most recently researching the influence of a changing fire frequency on carbon consumption in Alaskan black spruce forests.

    In my work for the Carbon Cycle and Ecosystems office at NASA I have moved into support science where I provide various types of support for the Arctic-Boreal Vulnerability Experiment (ABoVE) including geographical and data management, assistance in developing the ABoVE Science Cloud needs and requirements and even cartographic, GIS, web mapping and data display support.
