Short Bio

Before coming to Pitt-Bradford, Piechnik held two post-doctoral scholar positions at Penn State - University Park. Piechnik performed an ecological analysis of the arthropods of the Gettysburg National Military Park (Gettysburg PA) as a Research Associate with PSIEE and the Dept. of Entomology. She also performed research on GIS methods to place pasture-based Best Management Practices at the USDA-ARS Pasture Systems and Watershed Management Research Unit. Dr. Piechnik earned her dissertation at the University of California, Davis. Her dissertation is titled “Experimental Analysis of Spatial Relationships of Food-webs during Community Assembly.”

Research, Accomplishments, and Publications

Dr Piechnik's research interests include integrating approaches from community, landscape, and population ecology to understand mechanisms of biodiversity, and determining factors responsible for biodiversity patterns and their effects which produce complex patterns in natural and human-dominated systems. Dr. Piechnik is a member of the Ecological Society of America.
