  • NREM 1012: Introduction to Natural Resource Ecology and Management
  • NREM 2013: Ecology of Natural Resources
  • NREM 4464: Ornithology
  • NREM 4543: Wildlife Management for Biodiversity
  • NREM 5083*: Applied Landscape Ecology

Research Interests:
My primary work involves distribution and abundance of birds and mammals, habitat selection, ecological indicators, and the influence of human activities on wildlife populations, especially mortality from collision with human structures.
