Education

Ph.D., Ecology— Colorado State University, June 2006

B.A., Biology — Rice University, January 1999

Current or Recent Positions

Wildlife Habitat Researcher— Colorado Parks and Wildlife, June 2007-Present

Researcher— Natural Resource Ecology Laboratory, Fort Collins, CO, June 2006- May 2007

Current or Recent Research Projects

  • Researching improved techniques for restoring wildlife habitat following oil and gas
    disturbances
  • Understanding how weed seed dispersal is influenced by landscape features
  • Developing tools for creating microtopography to enhance seed establishment and limit weed seed dispersal
  • Quantifying understory responses to mastication (tree removal) treatments
  • Improving shrub measurement techniques
  • Understanding how drought, cheatgrass (Bromus tectorum) and a water-conserving soil amendment impact restoration in Colorado

Areas of Interest, Expertise

Invasive plant ecology; arid lands restoration techniques; plant-herbivore interactions; seed
dispersal; shrub measurement techniques; plant water relations
