Research Interests/Duties

My primary research objective is to develop knowledge to facilitate the use of prescribed fire. My education and experience in forest management and prescribed fire research at the former Southern Forest Fire Lab provided me an appreciation of the utility and challenges of prescribed fire use. Currently I am focused on the application and use of various models for fire behavior and fuel treatment. These models include fire spread models, fuel moisture models, and landscape level planning models.

Current Emphases, Studies, Projects
  • Marginal burning in chaparral and live fuels for prescribed fire application
  • Evaluation of fuel treatment planning models
  • Application of fuel moisture and fire behavior models to Hawaiian conditions
  • Potential application of prescribed fire in southern California forests
