Educational BackgroundPh.D., Ecology, Evolution & Behavior, University of Louisville, 2007Bachelor of Science, Biology, Xavier University, 2002
Professional BackgroundWhile still finishing my dissertation at the University of Louisville, I took a position at Alice Lloyd College in eastern Kentucky. In 2009, I got married and left my position at ALC to move to the Pittsburgh area with my husband-also a biologist- who took a job in the area. I was delighted to join RMU as an adjunct faculty member in 2009, and began as a full-time assistant professor in 2010.
Area of Expertise/ResearchI consider myself a broadly trained ecologist, with a specialty in behavioral ecology and zoology.
The majority of my research has been concerning reproductive behaviors- specifically how breeding sites are chosen and how anthropogenic changes influence behaviors.
Currently, I am investigating the effects of pesticides on the behaviors of a common predator of crop pests- the striped lynx spider, Oxyopes salticus.
Additionally, this spring, my students and I, in partnership with the Fern Hollow Nature Center, began marking Jeffersons salamanders to monitor how recent changes to their habitats affect their population and breeding behaviors.
