Current Research

Quantifying the effects of thinning and surface fuel treaments on Arizona's state largest recorded wildfire (Wallow Fire 2011), intergrating the Fuels Characteristic Classification System and Forest Vegetation Simulator, simulating fuel treatment alternatives on the South Shore Project (LTBMU).

Research Interests

Fire ecology, fire effects, silviculture, fuel treatments and fire behavior, simulation modeling, bark beeltes, climate change.

Past Research

My past work includes; studies of fuels planning and fuel treatments effects in dry forests of the Western United States, fire hazard assessment and decomposition study of Washington State's Cedar River Municipal,review of the effects of bark mortality on subsequent fire behavior Watershed examine the effects of salvage logging on fire behavior, fuel loading, fuel emissions, fuel consumption

Why This Research is Important

My research helps fire and forest managers make informed decisions based on current scientifc information.
