Personal Summary: 

Greg has been at the Fire Lab since 2004, working primarily in the areas of geospatial analysis, vegetation ecology, and fire ecology. He was the team lead for potential vegetation mapping on the National LANDFIRE project from 2004 to 2009, directing the creation of the Environmental Site Potential and Biophysical Settings geospatial products for the conterminous U.S. From 2009 to 2011 he worked on the FIRESEV project, using satellite-derived measures of burn severity to: a) examine relationships between burn severity and site conditions; and b) produce a predictive map of the potential for severe fire across the conterminous western U.S. Greg joined the Fire Modeling Institute in April 2011 and his work now is centered around application of the latest advances in spatial analysis and fire science to land management questions. Since 2013, much of his attention has been directed toward mapping efforts to support national strategic hazardous fuels prioritization and wildfire risk assessment work.

Prior to 2004, Greg worked as a GIS analyst with the Forest Service in Seattle, WA (Mt. Baker-Snoqualmie National Forest and Region 6 ecology program); Asheville, NC (National Forests in North Carolina); and Harrisonburg, VA (George Washington National Forest). He also worked as an Assistant Research Scientist with the University of Wyoming Botany Department.

When not at work, Greg enjoys making music, skiing, playing and refereeing hockey, running, and generally trying to keep up with his wife and two busy and energetic daughters.
