Current Research

My current work focuses on the Fire Program Analysis (FPA) Initial Response Simulator (IRS). Through an understanding of the details of the IRS I'm developing a description of how the program responds to changes in field input. With this knowledge I'm able to determine where the program is not performing effectively and am able to fix program errors and improve the it's performance and usability.

Research Interests

My research interests are in wildland fire suppression, the effectiveness of suppression resources, modified suppression efforts and wildland fire use.

Past Research

A lot of money is spent annually on wildland fire suppression. The fire program analysis is being developed to enable wildland fire managers from the fire federal land management agencies to jointly plan their wildland fire preparedness programs. Ensuring that the Initial Attack Simulator uses the best science available and provides accurate information to this planning process is an essential.

Why This Research is Important

My past research involved aerial suppression resources. Developing guidelines for airtanker delivery systems, and developing methods for efficiently deploying helicopters based on carrying capacity at altitude and temperature conditions.
