Research Biologist (Fire and Ecosystem Modeler) 8/2001 - present
In addition to continuing my scope of responsibility as a member of the MAPSS team (described below), I am embarking on a new multi-year research project funded by the National Fire Plan. My overall task is to enhance the predictive capacity of near-term fire risks and impacts over the conterminous United States. Individual tasks include validation and enhancement of exisiting continental-scale fire/ecosystem models, development of continuing near-term (3-12 month) spatially-explicit forecasts of fire weather, and production of continentally-mapped projections of near-term potential fire risk and impacts.
Research Associate 9/1992 - 8/2001
For over a decade I built process-based, large-scale models of ecosystem dynamics and natural disturbance as a member of the Mapped Atmosphere-Plant-Soil System (MAPSS) team, part of the USFS Pacific Northwest Research Station's Managing Natural Disturbance Regimes Program. My primary responsibility within the MAPSS team was to independently plan and conduct research to develop models that simulate the regional-to-global scale impact of altered fire regimes on the distribution, structure, and function of ecosystems and on the global carbon cycle. Working with other members of the team, I also designed and created large-scale earth system modeling structures that linked individual models of climate, vegetation, natural disturbance, and biogeochemistry. I designed and conducted coupled fire-ecosystem modeling experiments that addressed a variety of science and management issues (e.g., how sources and sinks of carbon might change naturally over time or be modified by management practices; the potential fire risk and impacts over a range of future climate scenarios; spatial and temporal scaling in multi-scale modeling applications). I contributed interpreted results of these modeling experiments to regional, national and international assessments and policy analyses relating to climate change impacts on vegetation, disturbance regimes, and carbon flux. I helped provide modeling tools for assessing adaptive management strategies for ecosystem management at multiple scales. I often conducted my research as part of interagency and interdisciplinary teams, and I secured support for my research through successful competition for grant funding. I published and presented my research in peer-reviewed journals and at scientific symposia, and I participated by invitation in international workshops that synthesized knowledge and theory from the global community of disturbance ecologists into a quantitative framework that will guide future work in disturbance ecology and modeling.
