Current Research

  • Characterizing patterns of tree regeneration following large wildfires in ponderosa pine forests
  • Exotic plants associated with mastication fuels treatments
  • Mycorrhizal status and surrounding soil properties of the endemic species, San Francisco Peaks ragwort (Packera franciscana)
  • Native shrub response to soil amendments and herbicide treatments used to control an exotic grass

Research Interests

  • Plant, soil and soil microbial response to wildfires and fuel treatments
  • Interactions between mycorrhizal fungi and native and exotic plants
  • Characterizing post-wildfire plant regeneration patterns
  • Disturbance and land management effects on ecosystem processes

Past Research

  • Soil,¬†soil microbe¬†and native/exotic plant responses to fuel reduction treatments
  • Soil amendment and plant neighbor effects on a native an exotic grass
  • Rehabilitating post-wildfire, cheatgrass invaded shrublands using Imazapic and seeding with native shrubs
  • Fuel treatments affect understory plant and soil community composition (mycorrhizal and PLFA profiles)
