  • Ph D Michigan State University 2006
  • MS University of Idaho 2000
  • BS University of Idaho 1999


I received my PhD from the Department of Fisheries and Wildlife at Michigan State University (MSU). Upon completion of my PhD I served as a postdoctoral researcher at the Quantitative Fisheries Center (located at MSU). The primary focus of the my research is on linking fine-scale lab and field studies within a macrosystems theoretical framework to understand ecological patterns and processes in aquatic systems across broad spatial and temporal scales.
