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).
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
Research Interest
Fire ecology, fire effects, silviculture, fuel treatments and fire behavior, simulation modeling, bark beeltes, climate change.
Why This Research Is Important
My research helps fire and forest managers make informed decisions based on current scientifc information.

Research Highlights
Scientists Study Salvage Logging After a Major Windstorm
Year: 2013
These results illustrate potential differences between the effects of salvage logging after windstorms and the effects of salvage logging after wildfire.
