Cailin Huyck Orr

Assistant Director
Science Education Resource Center - Carleton College

I joined SERC as the Assistant Director in June 2014. While I am excited about learning all aspects of SERC projects and approaches, my near-term focus will be on project management, particularly related to professional development, community visioning and bringing science into broader use. My background is strongly interdisciplinary with degrees in biology and limnology and postdoctoral training in geomorphology. My biophysical research has focused on ecological-physical interactions in stream and river dynamics and particularly nutrient cycling. I spent two years (2007-2009) working as a synthesis postdoctoral researcher with the National Center for Earth-Surface Dynamics at the St. Anthony Falls Laboratory in Minneapolis. Before joining SERC I was a faculty member in the School of the Environment at Washington State University for five years, working with collaborators in geosciences, engineering, economics, and communications on both stream ecology and also water sustainability and climate projects. I continue to work with graduate students at WSU who are interested in nitrogen and phosphorus dynamics in streams. I feel equally at home at meetings of the Ecological Society of America, Geological Society of America, American Geophysical Union and the Society for Freshwater Science.
