Currently a senior at Northern Arizona University and working towards a B.S. in Biology with a minor in Chemistry.  I am preparing for a career in research and instruction, through a variety of classes, fellowships, and volunteer opportunities.

Current research

I am working on a long term study examining the effects of elevated nitrogen (N) and carbon dioxide (CO2) on soil microarthropods. Experimentally testing these two parameters, which are both expected to increase over time, will broaden our knowledge about how ecosystems respond to global change.  Preliminary results indicate that increased CO2 causes a significant increase in Collembola populations. 

Past research and interests

In 2008, I was involved in a research project based on bat population dynamics.  This project took place in the Kaibab Paiute Indian Reservation, in northern Arizona.  The project entailed capturing and handling bats, marking them, identifying species, processing them, recording data and releasing them.  My project culminated in a presentation that encompassed data going back 10 years.  Interesting trends emerged with specific species richness fluctuations.

Other research interests include:

  • bioremediation
  • organic and sustainable agriculture
  • population dynamics
  • environmental toxins (especially those that act as teratogens)
