Research Interests

My research interests involve characterizing effects of fire and fuels treatments on forests. I am interested in these characterizations at both the stand and landscape levels. Active research areas include: 1) stand development/recovery following fuel reduction treatments and wildfires, 2) modeled effects of landscape fuel treatment networks, 3) fire severity patterns and interactions among managed wildfires in long-term natural fire areas, and 4) characterizing variability in forests under more natural fire regimes. My research intends to provide meaningful information to managers interested in improving forest resiliency and incorporating more natural fire-vegetation dynamics across landscapes.
