Hometown: Sloatsburg, NY
BA: Colgate University, NY
PhD: Utah State University


Dr. Marcarelli is an Assistant Professor at Michigan Tech University in Houghton, Michigan. Amy was a postdoctoral researcher at ISU from 2006-2009. She helped lead a collaborative project aimed at examining the effects of salmon marine derived nutrients on stream-riparian production, as well as a project investigating human effects on nutrient cycling and export from a mid-order river. She remains involved in those projects from her new position. Follow the link above to visit her individual web page.
