I was hired at Shippensburg University in 2000 as an Ecosystems Ecologist, after living and earning my graduate degrees in the Northeast U.S. My interests span ecological and hydrological sciences and I enjoy music (I am a cellist), fly fishing, gardening, upland hunting and other outdoor activities. I have three remarkable daughters who have grown up during my tenure at Shippensburg.

Research Interests

I am specifically interested in tracing sources of water, resources, and contaminants in ecosystems using fluorescence and isotopic techniques. I am broadly interested in applying an understanding of ecosystem function to best manage natural systems and resources and to solve environmental problems.

Courses Taught

  • Ecology
  • Ecosystems Ecology
  • Wetlands Ecology
  • Plant Ecology
  • Scientific Communication (Seminar)
