Current Research

As a spatial fire analyst with the Fire Modeling Institute, Greg works on varied projects that use geospatial technology to address land management and fire management questions. Current examples of projects include: 1) assessing wildfire risk across National Forest System lands in the conterminous United States; 2) producing and maintaining a map that depicts potential wildfire hazard across the United States (known as the Wildfire Hazard Potential map); and 3) mapping the potential for high severity fire across the United States using satellite data and statistical modeling.

Research Interests

Greg's work centers around geospatial analysis, vegetation ecology, and fire ecology. In his current position with the Fire Modeling Institute, he applies recent advances in fire science and geospatial technology to address management questions from the national level down to local districts.

Past Research

Prior to working for FMI, Greg worked in the Fire, Fuel, and Smoke Science Program on research to understand the topographic and climatic drivers of burn severity across broad regions in the western United States, and produced maps of the potential for high severity fire. He also was the team leader for mapping potential vegetation (ESP and BpS) on the national LANDFIRE project from 2004 to 2009. Before coming to the Missoula Fire Sciences Lab, Greg was a GIS Analyst for the USDA Forest Service Region 6 Area Ecology Program. There he assissted with mapping potential vegetation and predictive modeling of rare plant and animal species in Washington, Oregon, and Northern California. He also held GIS Analyst positions on the National Forests in North Carolina and the George Washington National Forest, and worked on syntheses of the historic range of variability (HRV) for upland vegetation on three National Forests in Wyoming.
