Karen Casciotti
Assistant Professor, Department of Environmental Earth System Science

Karen Casciotti is an Assistant Professor in the Environment Earth System Science Program at Stanford University. She received her Ph.D. in Geosciences in 2011 from Princeton University. From 2004-2010 she was a Scientist at the Woods Hole Oceanographic Institution MC&G Department. She came to Stanford in 2011. Her research focuses on nitrogen cycle biogeochemistry, including how nitrate, nitrite and nitrous oxide (N2O) are produced and consumed in ocean waters. Nitrate and nitrite are important nutrients for marine photosynthesis, and N2O is a climatically important trace gas. She takes an interdisciplinary approach to these questions, applying tools from stable isotope geochemistry, geochemical modeling, microbiology and molecular biology.
