Current Research

I lead efforts to develop (1) a natural fuels photo series for the United States, Mexico, and Brazil; (2) the Consume model, which predicts fuel consumption and emission production by combustion phase for forested and non-forested fuel types across North America; and (3) the Fuel Characteristic Classification System, which characterizes fuelbeds for the United States and the world. I consult on the assessment of wildland firefighter exposure to smoke and the associated health risks and also lead the Prescribed Fire Combustion and Atmospheric Research Experiment (RxCADRE), a group of individual researchers and research teams from across the United States which is instrumenting and collecting data that will complement each area of research in the pre-, active, and postfire burning periods of prescribed burns.

Research Interests

Fuelbed characteristics, fuel moisture, fuel consumption, smoke management, firefighter exposure to smoke, and technology transfer of science.

Past Research

I have been involved with fuels, fire, and smoke-related research for over 35. In my early career, I lead efforts to modifiy and improve the the natural fuels photo series and develop models for predicting fuel consumption and emissions for smoke management planning. Later, I become interested in firefighters and their exposure to smoke both on the fireline and in camp and in developing a system to better characertize fuelbeds for fire planning.

Why This Research is Important

Whether it is prediction of fire behavior variables such as flamelength and rate of spread, fire effects such as smoke, air quality impacts, carbon release, tree mortality, or mineral soil exposure, a comprehensive characterization of fuelbeds and consumption of the fuelbed components by combustion stage are required. In addition, firefighter exposure to smoke and the resulting short-term and long-term effects are not well understood. Further research is needed if appropriate firefighter risk management strategies are to be developed.
